Shipping Container Lock Box

This shipping container lock box is a heavy-gauge steel enclosure that bolts onto a container's cargo doors to protect the padlock shackle from bolt cutters, angle grinders, and other cutting tools. A padlock used alone leaves its shackle exposed and can be cut through in under ten seconds; enclosing it inside this steel housing, with a recessed bolt design that also resists prying, closes that gap. Installation requires no welding. The kit includes a two-piece enclosure (left and right door halves), Grade 5 carriage bolts with hidden heads, backing plates that double as drill templates, washers, and mounting hardware, along with installation instructions. With a drill, a 5/8-inch bit, a 3/4-inch socket wrench, and basic measuring tools, installation typically takes 15 to 20 minutes: position the lock box at the preferred height (42–60 inches from the ground), mark the drill holes using the backing plate as a template, drill through the container doors, insert the carriage bolts through the lock box, door, and backing plate, then tighten. The finish is powder-coated steel, built to resist rust and hold up in outdoor conditions. It fits standard ISO 20-foot and 40-foot shipping containers with traditional swing doors and locking-rod handles, across New (1-Trip), Multi-Trip, Wind and Water Tight, Cargo Worthy, and most As-Is container grades, though the hardware isn't designed for roll-up door conversions, damaged or modified locking rods, or other non-standard door configurations — contact us to confirm fit if your container has been modified. A padlock is not included; pair it with a heavy-duty disc lock or shrouded-shackle padlock rated for outdoor use. If your lock box arrives with a defect in materials or workmanship, we'll arrange a replacement or refund.
