DEE ZEE DZ91717P Poly Triangle Trailer Box
The Dee Zee DZ91717P is a poly triangle trailer box with a rigid frame and a double wall lid. It’s best for buyers who want warp resistance and a sturdy lid to support extra weight on top. The classic Brite-Tread pattern adds exterior grip and a durable finish. Choose this if you need a compact, weather-resistant box for standard trailer chores and light tools. Caution: polyethylene can be prone to denting under heavy direct impact.
AB Tools Trailer Truck Plastic Lockable Toolbox
The AB Tools box is a compact, lockable plastic chest designed for secure storage of tools and straps on trailers. Its external dimensions translate to roughly 550mm x 255mm x 310mm, making it a good choice for limited spaces. Best for budget-conscious buyers who still want tool protection and secure access. Limitation: smaller capacity means you may need multiple units for larger tool sets.
Overland Vehicle Systems 53 Qt Dry Box
The Overland Dry Box stores up to 53 quarts and emphasizes waterproof sealing and easy transport. It features heavy-duty latches and ballistic handles for better handling on rugged terrain. Best for off-road enthusiasts needing dry gear protection and reliable sealing. Caution: heavier when fully loaded, which can affect vehicle handling if misused on lightweight trailers.
Garvee 30-Inch Black Steel Box
The Garvee steel box uses 12-gauge steel with a textured powder coating for durability in extreme temperatures. It’s best for contractors or tailgate setups where quick access matters, thanks to its no-lock, open design and a 110-degree opening. Choose this if you need fast gear access and rugged construction. Limitation: no integrated lock means extra security considerations if left unattended.
Buyers Products 1707020 Cargo Chest
The Buyers Products cargo chest combines high-density polyethylene storage with a steel frame and a weatherproof, hitch-mounted design. Its large capacity and durable frame make it ideal for frequent highway or trailer use where weather protection and sturdy mounting are essential. Best for owners needing integrated storage with a robust frame. Caution: the combination of plastic chest and steel frame may require periodic corrosion checks on exposed hardware.
Buying Guide: What To Consider When Choosing Polyethylene Trailer Boxes
- Storage capacity: Match box size to the gear you carry. Larger boxes provide more space but add weight and may require bigger hitch setups.
- Weather sealing: Look for waterproof seals and double-wall construction for moisture protection and impact resistance.
- Security: If frequent unattended use is expected, prioritize locked lids or lockable options and consider adding padlocks where needed.
- Mounting and access: Ensure compatibility with your trailer, hitch, or truck bed. A 110-degree lid opening can improve access in tight spaces.
- Material durability: Polyethylene resists impact and weather, while steel options give maximum rigidity but weigh more and may require coatings to resist corrosion.
- Portability: For lightweight needs, plastic boxes with integrated handles are easier to move; for heavy gear, consider reinforced handles and latching systems.
- Maintenance: Check for UV resistance, easy-to-clean surfaces, and secure fasteners to prevent rattling during transport.
