Rust-proof, element-proof protection: the Rustrictor Field/Ammo Box Compact promises a secure storage solution for everything from ammo to fishing gear. Rustrictor technology blocks corrosion and rust, while the brass-bailed latch and water-resistant O-ring seal keep everything else out. The storage box is sized to hold up to 4 shot shell boxes, but its compact footprint also makes it a great catchall for general storage in a garage or shed.
