Plano Waterproof StowAway Utility Box - 3700 Size

The Plano Waterproof StowAway Utility Box – 3700 Size is purpose-built for anglers, boaters, and anyone who needs reliable dry storage in challenging environments. Over years on the water, you learn that moisture and salt spray are the silent killers of gear—corroding electronics, degrading tackle, and ruining equipment worth far more than the box itself. This compact utility box solves that problem with military-grade waterproof engineering at a price that doesn't require a second mortgage, making it an essential companion for deck storage, tackle organization, or emergency supplies.

The key to its reliability is the Dri-Loc O-ring seal system, which creates an airtight barrier that keeps water, humidity, and contaminants completely out. The three tight-sealing latches work together to compress and hold that seal uniformly across the lid, preventing the common failure point where cheap boxes flex under pressure and lose their water resistance. Measuring 9 × 2 × 14 inches and weighing just 1.3 pounds, the 3700 Size strikes the right balance—large enough to hold spare reels, first-aid kits, electronics, or small tools, yet compact enough to stow in a console, under a seat, or in a tackle bag without adding bulk.

This box performs equally well on freshwater and saltwater vessels, in kayaks, cabin cruisers, or offshore rigs. Anglers trust it for storing lures and terminal tackle away from humidity that promotes rust; boaters rely on it for keeping navigation documents, medications, and backup electronics dry. Its rugged construction also serves contractors, hunters, and outdoor enthusiasts who need to protect small parts, batteries, or valuables from the elements during extended time in rough conditions.
