These ammo crates are designed for both short and long-term storage for your ammo, firearms, survival gear or pretty much anything else. The high-impact polypropylene plastic construction is built for durability and will withstand the test of time and endure some pretty extreme treatment. Each one also provides heavy-duty dual latches, three padlock tabs and molded-in stacking ridges for slip-resistant stacking. Their deep but fairly compact size allows you to store them efficiently in a variety of locations such as your basement, garage, or storage shelves. Best of all, each one is proudly made in the U.S.A.
