Domestic Security

When replacing a door and buying a new lock, one should expect to pay almost as much for the lock as for the door. Economising on the lock could prove to be very costly in the long run. A number of security door knobs have their own deadbolt lock attached, to provide either primary or auxiliary locking, with the key being inserted into the locking device of the doorknob. Others have the deadbolt lock combined with a latch to give the safety of a 'panic-proof exit.

A turn of the inside lever retracts bolt and latch simultaneously. These door knobs are available in brass, bronzed finish and chrome.
