Waterproof Utility Box W/ O-ring

The Plano Waterproof Utility Box with O-ring (Model 354010) is a compact storage solution designed for anglers, boaters, and outdoor enthusiasts who demand reliable protection for tackle, tools, and small parts in harsh marine environments. Built by Plano—a trusted name in waterproof gear for decades—this lightweight case addresses a universal need: keeping critical items dry and organized while on the water or in unpredictable conditions.

Its modest footprint (9.1 x 1.8 x 4.8 inches) and half-pound weight make it ideal for stowing in rod holders, tackle bags, or boat cabins without sacrificing security. The engineering behind this box centers on two proven sealing mechanisms: a Dri-Loc O-ring seal that creates a moisture-tight barrier around the lid perimeter, and three cam action latches that lock contents down firmly even during rough seas or transport. The O-ring design is the gold standard in waterproof storage—it compresses against the case lip as latches tighten, forcing water out and preventing seepage even when partially submerged.

Seasoned anglers favor this box for storing spare hooks, weights, terminal tackle, batteries, first-aid supplies, and small hand tools—anything that degrades or fails when wet. The compact size works equally well for various outdoor applications, ensuring that your essential gear remains protected from the elements.
