Orangeville, ON (Harold Doan and Sons Ltd.) For commercial and industrial customers, the first line of defence against burglary is the hardware on the doors. This commercial hardware consists of a wide variety of locks and locking systems. Many of these are heavy-duty versions of residential locks, but other locks are found only in commercial applications.

Probably the most common commercial hardware is found on glass doors. Deadbolts, deadlatches, and exit devices can all be found on glass doors. There are many manufacturers of deadbolts and deadlatches for these doors, but they are all very similar.

The standard deadbolt has a flip-up type bolt made of laminated steel and uses a mortise type cylinder. For applications with a narrow depth of frame, a shorter flip-up bolt is available. For added security against crowbar attacks, hook type flip-up bolts are used.

Deadlatches for these doors can be activated from inside with either a lever handle or a paddle-type handle. The paddle handle is much more durable and can be easily serviced. This more than offsets their added initial cost.
