SlamCAM, a spring loaded latch, along with the self-locking component, converts CompX National cam locks (C8051-C8075) into self-locking. SlamCAM — spring loaded latch Replacing steel cams with SlamCAM eliminates steel cams that crash into furniture or strikes while in the latched position. Bent cams can cause locks not to secure properly or secure at all. Self-locking The self-locking feature uses spring tension to conveniently return the lock to the locked position. User turns the key to the open position and opens the door or drawer. Upon releasing the key, the self-locking component returns the lock along with SlamCAM to the locked position; user simply closes the door or drawer — no need to turn the lock back to the locked position.
