    Package Delivery Box for Outside, Large Parcel Drop Box with Lockable Secure, Waterproof and Anti-Theft Storage for Porch, Curbside, House (Black)

    Best Overall

    View Latest Price

    This delivery box stands out for its combination of weatherproof durability and security, making it ideal for those seeking reliable outdoor parcel storage. Unlike the Merapi steel model, it offers a sleek, modern resin exterior that resists corrosion and blends into most outdoor settings. Its innovative 1-way, 2-tray system simplifies parcel dropping without compromising security. However, the locks are sold separately, which can be an inconvenience for buyers wanting an all-in-one solution. This model’s large capacity and weatherproof design make it perfect for homeowners with frequent deliveries, but it may be heavy to move once filled.

    Pros:
    • Weather-resistant and durable resin construction
    • Secure lockable design prevents theft
    • Large capacity accommodates multiple packages
    • Modern, stylish appearance
    Cons:
    • Locks are not included and must be purchased separately
    • Can be heavy when filled with packages

    Best for: Homeowners needing a weather-resistant, lockable solution that fits multiple packages without frequent maintenance

    Not ideal for: Buyers seeking a lightweight, portable option or one with integrated locks included

    • Material:All-weather resin
    • Features:Lockable, waterproof, anti-theft, 1-way 2-tray system
    • Capacity:Generous interior space
    • Color:Black
    Our verdict
    “This option is best for homeowners who want a stylish, weatherproof, and secure outdoor parcel box with ample space.”
  2. Step2 Lakewood Package Delivery Box, Large Capacity Outdoor Parcel Drop Box with Lockable Lid and Keys, Weather-Resistant Resin, Dark Cedar

    Compared with the more premium Merapi steel option, the Step2 Lakewood offers a generous capacity with a lockable lid, making it a practical choice for those on a budget. Its weather-resistant resin construction ensures packages stay dry, and the included lock and key add a layer of security. Yet, this model requires anchoring or weighting for stability, which could be a drawback for renters or those seeking an easy-to-move option. Its large capacity is ideal for households with frequent deliveries, but the limited color choices might not suit all outdoor aesthetics.

    Pros:
    • Large capacity fits many packages and envelopes
    • Weather-resistant resin protects deliveries
    • Includes lock and key for security
    • Compatible with ground anchors for stability
    Cons:
    • Requires anchoring or additional weight for stability
    • Limited color options, mainly dark cedar

    Best for: Budget-conscious homeowners or renters needing a large, lockable outdoor parcel box with straightforward security

    Not ideal for: Those who want a fully portable or decorative solution without the need for anchoring

    • Interior Capacity:Extra-Large
    • Material:Weather-Resistant Resin
    • Color:Dark Cedar
    • Locking Mechanism:Lock and Key
    • Base Capacity:Up to 100 lbs. (45.4 kg)
    Our verdict
    “This model suits budget-minded users who prioritize capacity and weatherproofing over ease of mobility.”
  3. Merapi Large Anti-Theft Package Delivery Box for Outside 43.3” x 18.3” x 14.0”, Lockable, Weatherproof Steel Storage for Porch and Curbside

    Merapi Large Anti-Theft Package Delivery Box for Outside 43.3” x 18.3” x 14.0”, Lockable, Weatherproof Steel Storage for Porch and Curbside

    Best Premium Steel Security

    View Latest Price

    The Merapi steel delivery box stands out for its rugged, pre-assembled construction, offering maximum security and strength. Compared with resin options like the Package Delivery Box for Outside, it provides superior theft resistance thanks to its reinforced locks and steel monocoque body. While this makes it highly durable and weatherproof, it requires ground anchoring for optimal security, adding complexity to setup. Its all-steel design makes it heavy and less portable, but for those prioritizing security above all, this model delivers unmatched robustness.

    Pros:
    • Heavy-duty, steel construction for security
    • Pre-assembled for quick setup
    • Large capacity fits multiple parcels
    • Weatherproof and rust-resistant
    Cons:
    • Requires ground anchoring for security
    • Heavy and difficult to move

    Best for: Homeowners or small business owners needing the highest level of theft protection in a large, weatherproof steel enclosure

    Not ideal for: People seeking a lightweight or decorative box, or those who dislike assembly or anchoring

    • Dimensions:43.3” x 18.3” x 14.0”
    • Material:Steel
    • Lock:Reinforced, pick-resistant
    • Keys:6 keys included
    • Weatherproof:Yes
    Our verdict
    “This pick is ideal for security-focused users willing to install a permanent, steel-based parcel solution outside.”
  4. Package Delivery Boxes for Outside, 120 Gallon Outdoor Storage Box

    Package Delivery Boxes for Outside, 120 Gallon Outdoor Storage Box

    Best for Large Capacity and Versatility

    View Latest Price

    This 120-gallon storage box combines large capacity with outdoor durability, making it suitable for both package delivery and general storage needs. Its waterproof, UV-resistant construction and lockable lid protect items from the elements. Compared with resin or steel options, this box offers a more versatile storage solution that can also hold outdoor gear or tools. However, the heavy weight when fully loaded and the need for assembly may deter some buyers. Its stylish woodgrain finish adds a natural touch to outdoor spaces, but its primary focus is on capacity and weather resistance rather than security against theft.

    Pros:
    • Huge 120-gallon capacity for packages and outdoor gear
    • Waterproof and UV-resistant for all weather
    • Lockable lid enhances security
    • Stylish woodgrain finish integrates with outdoor decor
    Cons:
    • Heavy when fully loaded, making relocation difficult
    • Requires assembly

    Best for: Homeowners needing a multi-purpose outdoor storage solution that can also serve as a large parcel drop box

    Not ideal for: Users who require high-security features or a lightweight, portable option

    • Capacity:120 gallons
    • Material:Dual-layer waterproof and UV-resistant
    • Features:Lockable, easy to clean, quick assembly
    • Finish:Woodgrain
    Our verdict
    “This storage box is best for those who want extensive outdoor capacity with weatherproofing and versatility over high security.”
  5. Suncast 33.5-Gallon Capacity Package Delivery Box with Lock

    Suncast 33.5-Gallon Capacity Package Delivery Box with Lock

    Best Compact Lockable Box

    View Latest Price

    The Suncast delivery box provides a reliable, lockable solution for smaller parcels, standing out for its compact size and ease of use. Compared to larger options like the Package Delivery Box for Outside or Merapi, it’s better suited for users with limited space or fewer delivery needs. Its weather-resistant resin construction offers decent protection, but its smaller capacity limits it to packages up to approximately 14 x 18 x 8 inches. While easy to maintain and assemble, this model may require frequent clearing if you receive multiple large deliveries regularly.

    Pros:
    • Secure, lockable design ensures safe deliveries
    • Weather-resistant for outdoor conditions
    • Easy to assemble and maintain
    • Compact size fits in tight spaces
    Cons:
    • Limited to packages no larger than 14 x 18 x 8 inches
    • Small capacity may require frequent emptying

    Best for: Urban residents or small households with limited outdoor space needing secure, smaller parcel storage

    Not ideal for: Homes with frequent large deliveries or multiple packages at once

    • Capacity:33.5 gallons
    • Dimensions:14 in. x 18 in. x 8 in.
    • Material:Heavy-duty resin
    • Made in:USA
    Our verdict
    “This pick is ideal for small households needing a secure, space-efficient parcel box for modest deliveries.”
  6. KAER Anti-Theft Package Drop Box, 44.5″ H Large Lockable Parcel Delivery Box, Waterproof Heavy Duty Steel Drop Box for Outside, Porch, Home & Business

    KAER Anti-Theft Package Drop Box, 44.5" H Large Lockable Parcel Delivery Box, Waterproof Heavy Duty Steel Drop Box for Outside, Porch, Home & Business

    Best for Heavy-Duty Security and Long-Term Outdoor Use

    View Latest Price

    The KAER Anti-Theft Package Drop Box stands out for its robust galvanized steel construction and ground-mounted design, making it ideal for environments where theft prevention is a priority. Compared to the Package Delivery Box for Outside, 60 Gallon, which offers more capacity but uses resin, KAER’s steel build provides superior tamper-proof durability, especially in harsh weather. The dual compartments help organize deliveries, but its heavy weight and need for permanent installation mean it isn’t suited for those who frequently relocate or lack mounting space. Its weatherproof rating of IPX3 ensures reasonable rain resistance, though it’s not fully waterproof in extreme conditions. This pick makes the most sense for homeowners or small businesses seeking a permanent, secure outdoor solution with a focus on durability and theft deterrence.

    Pros:
    • Heavy-duty, tamper-proof galvanized steel construction for maximum security
    • Weatherproof design withstands rain and snow
    • Dual compartments improve organization of deliveries
    • Can be securely mounted to prevent theft
    Cons:
    • Requires installation and mounting hardware, which can be complex
    • Heavy weight makes relocation difficult after installation
    • Limited color options (neutral finish)

    Best for: Homeowners or small business owners who need a highly secure, permanently installed outdoor parcel box resistant to theft and weather.

    Not ideal for: Renters or users preferring portable solutions, as this requires ground mounting and is heavy to move once installed.

    • Height:44.5 inches
    • Material:Galvanized steel
    • Waterproof rating:IPX3
    • Installation:Permanent, ground-mounted
    • Compartments:Dual (mail and packages)
    Our verdict
    “This is best suited for users who prioritize durable, permanent outdoor security over portability.”
  7. Package Delivery Box for Outside, Parcel Drop Box, Black, 60 Gallon

    Package Delivery Box for Outside, Parcel Drop Box, Black, 60 Gallon

    Best for Large Capacity and Easy Access

    View Latest Price

    The Package Delivery Box for Outside offers a generous 60-gallon capacity, making it an excellent choice for households expecting multiple deliveries daily. Its resin construction is weatherproof and durable, providing good protection against the elements, though it’s not as heavy-duty as the steel KAER model. Compared with the KAER Drop Box, this box emphasizes ease of use with its simple assembly and the inclusion of a delivery sign, making it accessible for users who want straightforward setup. Its anti-theft design features a one-way entry, but it’s less secure than a permanently mounted steel box, so it’s better suited for those who need capacity and convenience rather than maximum security. This box makes sense for busy families or small offices that prioritize large volume storage and quick access.

    Pros:
    • Large 60-gallon capacity handles multiple parcels at once
    • Weatherproof resin construction resists the elements
    • Easy to assemble with included accessories
    • Anti-theft device with one-way entry for security
    Cons:
    • Heavy to move once assembled, limiting portability
    • Limited color options, only available in black
    • Less durable than steel options for long-term outdoor exposure

    Best for: Families or small business owners needing large capacity, weatherproof delivery storage that is easy to set up and access.

    Not ideal for: Users with high theft concerns or those in high-risk areas, since it’s portable and less tamper-proof than steel options.

    • Color:Black
    • Capacity:60 Gallons
    • Material:Resin
    • Features:Anti-theft device, weatherproof, delivery sign
    Our verdict
    “This pick is ideal for those who want a spacious, easy-to-use outdoor parcel box with good weather resistance, but less focus on theft prevention.”

Factors to Consider When Choosing Best Lockable Package Delivery Box Large Capacity

Choosing the right lockable large capacity delivery box involves understanding several critical factors that go beyond just size and security. Considering these aspects can help avoid common pitfalls like underestimating weather exposure or overpaying for features you don’t need. A well-chosen box can protect your packages, deter theft, and withstand the elements for years to come.

Capacity and Size

Size matters when you want to store multiple packages or large parcels. Larger capacity boxes, such as those over 100 gallons, can accommodate bigger deliveries but often come with increased weight and installation challenges. Make sure to measure your available space carefully and consider how frequently you’ll need to access stored parcels to choose a size that fits your routine.

Security Features

Security is paramount in preventing theft. Look for sturdy locking mechanisms—keys, digital locks, or padlocks—that suit your comfort level. Steel and anti-theft reinforcements add peace of mind, but heavier materials may require more effort to install or move. Consider whether a lockable lid alone suffices or if additional features like alarms are necessary.

Weather Resistance

Outdoor placement demands protection against rain, snow, and sun. Waterproof seals, rustproof materials, and UV-resistant finishes prolong the life of your delivery box. Cheaper or poorly sealed models may leak or corrode over time, defeating their purpose. Evaluate the environmental conditions in your area to select a truly weatherproof option.

Build Quality and Material

The choice between steel, resin, or composite impacts durability and weight. Steel offers high security but can be heavy and prone to rust if not treated properly. Resin models are lighter and resistant to corrosion but may not be as robust against theft. Balancing weight and strength according to your installation needs is essential.

Ease of Installation and Maintenance

Simplicity in setup and upkeep influences long-term satisfaction. Lightweight models are easier to install, while those with minimal moving parts tend to require less maintenance. Consider whether you need features like removable trays or easy access points to simplify daily use and cleaning.

Frequently Asked Questions

Will a larger capacity delivery box be more vulnerable to theft?

Not necessarily. While bigger boxes might be more tempting targets, many large models incorporate robust security features like steel construction and high-quality locks that deter theft effectively. It’s important to balance size with security, choosing a model that offers both ample storage and strong protective measures to prevent unauthorized access.

Can I install a large delivery box myself?

Most large delivery boxes are designed for straightforward installation, often requiring just a few tools and some basic instructions. However, heavier steel models might need additional help or specific anchoring methods to ensure stability. Carefully review the installation instructions and consider your physical ability or enlist help if needed to ensure safety.

Are lockable delivery boxes weatherproof enough for all climates?

Many models claim weather resistance, but their effectiveness varies with the environment. Look for models with sealed doors, rustproof materials, and UV-resistant finishes if you face harsh weather conditions. Proper installation, like anchoring to prevent tipping, also enhances weather durability and security over time.

What’s the best material for a long-lasting large capacity delivery box?

Steel is generally the most durable and secure option, especially if treated or coated to resist rust. Resin or composite options are lighter and corrosion-resistant but may not offer the same level of theft protection. Your choice depends on whether security or ease of handling takes priority, along with climate considerations.

How do I prevent my delivery box from becoming a target for theft?

Choosing a heavy, steel-built model with a high-security locking mechanism is key. Installing the box in a visible, well-lit location can also discourage theft. Additionally, anchoring the box firmly to the ground minimizes the risk of theft by making it harder to move or tamper with. Combining these strategies enhances overall security.

Conclusion

The best overall pick for most buyers is the Package Delivery Box for Outside thanks to its combination of size, waterproofing, and anti-theft features. Those seeking the best value might prefer the Suncast 33.5-Gallon Capacity Box for its affordability and decent security. For premium security and heavy-duty durability, the Merapi Large Anti-Theft Delivery Box delivers exceptional steel strength. Beginners or casual users will find the Step2 Lakewood straightforward and easy to install, while those with larger parcels or specific security needs should consider the 120-gallon options. Ultimately, your choice depends on your space, budget, and security priorities.
