Garage Door Side Locks for 2" or 3" Latch 7 1/4". Width: 4 3/4".
This interior keyless lock is fastened along the left or right side of the garage door, and has a sliding bolt that easily pushes through a square in the vertical track to securely lock the garage door in the closed position.
It is bigger and longer with more screw holes than the residential versions.
Installing on one side will typically provide ample security, but in some cases, you may wish to include a lock on both sides.
A padlock or combo lock can also be used with this type of slide lock to provide even more security.
