Used shipping containers in Oklahoma rarely come equipped with a lock box, which is basically a house for your padlock that prevents would-be intruders from cutting the shank and breaking into your unit.
For a small investment you can either have a lock box installed at a depot, or if the unit is already on-site (or welding equipment isn’t available) you can purchase and install a bolt on lock box in a matter of minutes.
To learn more, visit ContainerLockBox.com where you can purchase one online, or find a local retailer that can help you buy and install one.
