Do you require your equipment to be locked away or so no one can see what you have on your shelf? Why not add a locking door front kit to your shelf. This will add security and organization to any divider shelf or retainer lip. All doors are constructed from aluminum with double returned flanges on three sides for a smooth front and a superior rigidity. In combination with a shelf back and a shelf blocker, you can create a lockable compartment in any length of shelf. It includes all necessary hardware. Will not work on bin shelving. Depending on level of trim on your vehicle, modifications may be required.
