Flip up both latches, one on each side of the lock. With the latches in the upward position, flip the metal wire loops that are connected to the clasps down. The metal loops resemble the straps on a pair of overalls.
Insert the key or enter the combination of the lock connected to the tool box. Toolboxes come built with a center hole where you can place a lock to secure your tools. The lock is not included.
Pull down on the lock to open it and remove it from the center hole. Open the lid, some tool boxes have an additional metal latch that needs to be lifted up before the lid can be opened.
