VEVOR Trailer Tongue Box, 39″ Wide Aluminum, Lockable
Best for: jet ski owners needing substantial under-deck storage space. This aluminum tongue box offers a large interior (39″ x 16.5″ x 12″), suitable for batteries, tools, and outdoor gear. The aluminum construction emphasizes rust and wear resistance, while the overlapping doors and wide sealing strips improve weather protection. Choose this if you want a roomy, durable chest that remains easy to handle and install on various trailers. A potential limitation is its weight; despite being aluminum, the size adds handling effort on smaller installations.
DEE ZEE DZ91717P Poly Triangle Trailer Box
Best for: budget-conscious buyers seeking a weather-resilient, lightweight plastic box. The rigid plastic frame reduces warping risks, and the double wall lid adds protection against impacts. Its classic Brite-Tread pattern helps with grip and durability in dusty or muddy environments. Notable caveat: plastic construction may offer less impact resistance in very harsh environments compared to metal options, and the product lacks explicit locking hardware in some listings.
VEVOR Trailer Tongue Box, Steel, Lockable
Best for: users who want a steel, lockable option with robust construction for harsher environments. This model emphasizes security with a dedicated lock system and a sturdy hinge design. Better for: frequent use in off-road or industrial settings where metal resilience matters. Choose this if you prioritise security and durability and are comfortable with heavier hardware; potential limitation is weight and installation complexity on small trailers.
Buyers Products 1701380 Diamond Tread Aluminum Tongue Box
Best for: heavy-use trailers needing corrosion resistance and a weather-tight seal. The diamond tread aluminum provides a rugged exterior and corrosion resistance, while a continuous hinge and lid cable reduce wear. This option is ideal for work trailers and frequent-to-load scenarios. Limitation: it might be larger than needed for tiny trailers or tightly spaced tongue areas, so measure carefully before purchase.
Buyers Products 1701281 Gloss Black Steel Tongue Box
Best for: buyers seeking a compact, secure steel option with a sleek, weather-sealed finish. Its 15-gauge carbon steel construction offers ruggedness and a glossy finish that resists rust with proper care. The stainless paddle latch with two keys provides theft protection, and a continuous hinge supports durability. Better for smaller trailers or limited storage areas where a slim profile matters; limitation is higher weight for its size compared to some aluminum models.
Buying Guide
What material should I choose?
Aluminum offers lightweight strength and corrosion resistance, making it ideal for marine environments like jet ski trailers. Steel is typically tougher but heavier and may require protective coatings to resist rust. Plastic boxes are affordable and lightweight but can be less durable in extreme conditions.
What size do I need?
Measure your trailer tongue length, available space, and anticipated gear. Large interiors (like 39″ by 16.5″ by 12″) suit batteries, tools, and spare gear. Small boxes (around 12″ to 27″ in length) fit tight spaces and offer secure storage for essential items without bulk.
Is locking security important?
Yes for theft prevention and weather safety. Look for stainless or heavy-duty latches with two keys, weather seals, and reliable hinges. Some boxes include built-in locks; others rely on external padlocks or keyed latches.
Weather resistance and seals
Overlapping doors, wide sealing strips, and weather-tight gaskets help block water intrusion. If you trailer in rain or near saltwater, prioritize boxes with proven seal designs and corrosion-resistant hardware.
FAQ
- Do these boxes fit both A-frame and straight-tongue trailers? Most models are designed for both, but always verify the mounting compatibility and clearance on your specific trailer.
- Are the keys included with all models? Many options include keys for locking latches; some listings may require an additional purchase for a lock kit.
- Will these boxes rust? Aluminum boxes resist corrosion well; steel boxes may rust if not coated or maintained. Use proper care per manufacturer guidelines.
- Can I install these boxes myself? Yes, most tongue boxes are designed for DIY mounting with standard tools and mounting hardware provided or available separately.
- What maintenance is required? Regularly inspect seals, hinges, and latches; clean interiors to prevent corrosion buildup; lubricate moving parts as needed.
