This a keylock with disc tumblers, made by Comp-X National. These are keyed alike and come unassembled. Included in the package is 2 keys as well as two cams (one straight and one offset) and a spur washer for installation in wood or softer materials. This prevents the lock from spinning in the hole when being used.
This is an excellent lock for any wood or metal cabinets, toolbox or other type of enclosure.
