Plano Waterproof Polycarbonate Storage Box - 3500 Size - Orange/Clear

A waterproof storage box is essential gear for anyone who spends time on the water, in the field, or anywhere conditions demand rock-solid protection for small valuables. The Plano Waterproof Polycarbonate Storage Box – 3500 Size fills that role with practical, proven engineering. Whether you're securing a wallet, phone, camera, or other electronics during a fishing trip, backcountry hunt, or water-based adventure, this compact case keeps contents safe and completely dry thanks to its Dri-Loc O-ring seal and cam-action latches that lock down an airtight environment.

Built for real-world conditions, the 3500 box is submersible to one meter for up to 30 minutes—meaning even an accidental dunking won't compromise your gear. The interior slip-resistant rubber pad prevents fragile items from shifting around, and a wrist strap tethers the box to your pack, boat, or belt so it won't get left behind. The polycarbonate construction is lightweight without sacrificing durability, and the high-visibility orange exterior with clear lid makes locating your box and seeing contents at a glance straightforward.

At 7.5 inches long by 3.125 inches wide and 2.5 inches deep inside, the 3500 is sized for the essentials—a smartphone, a set of keys, a small camera, or a folded ID and cash—without the bulk of larger cases. If you're overlanding, fishing, kayaking, hunting in wet terrain, or simply want a reliable dry box for day trips, this Plano case delivers the protection you need without overthinking it.

Frequently Asked Questions

What can fit inside the Plano 3500 waterproof box?

With interior dimensions of 7.5″ L × 3.125″ W × 2.5″ H, the 3500 is sized for compact valuables: smartphones, car or house keys, a wallet, a small camera, credit cards, cash, or other electronics you want to keep dry. It's not designed for larger items or multiple cameras.

Is the Plano 3500 truly waterproof if submerged?

Yes. The Dri-Loc O-ring seal and cam-action latches create an airtight, waterproof environment. The box is submersible to one meter of depth for up to 30 minutes, so accidental dunking in a river, lake, or ocean won't let water inside. For extended submersion or deeper water, confirm your specific use case against this rating.

Will the rubber pad inside protect my camera or phone?

The interior slip-resistant rubber pad is designed to prevent items from shifting and sliding around inside the case, which helps protect fragile gear from impact damage during transport and use. However, it is not a foam insert or custom-fit padding—it provides basic cushioning and grip, not shock absorption equivalent to specialized camera cases.

What comes with the box?

The Plano Waterproof Polycarbonate Storage Box – 3500 Size comes with the case, Dri-Loc seal, cam-action latches, interior rubber pad, and a wrist strap. No additional inserts, locks, or accessories are included.
