Heavy Duty Deadbolt D103 SC

Door latches are popular as an additional means of security in residential and commercial applications. These Heavy Duty Deadbolt Locks use a key on the outside and a key or thumb on the inside to throw solid bolts in and out of the door frame. The deadbolt is difficult to force open, so it provides extra protection against theft.

Using a key-operated deadbolt inside can be dangerous in an emergency if the key is not easily accessible. Therefore, it is recommended to keep the key in the lock or in an easily accessible place near the door. However, care should be taken to ensure that the key or thumb knob is not accessible through a window on or near the door, which will make it easy for a burglar to unlock the deadbolt.
