LOSSARY

Auxiliary lock

A lock having a latchbolt or deadbolt operated by a key or a thumbturn or both. This type of lock is often used in conjunction with another lock which may or may not be key operated, but has a latchbolt operated by knobs or levers.

Bored deadlock

A lock that fits round, bored holes drilled into the face and edge of a door. Bored deadlocks have a deadbolt operated by a key or thumbturn or both.

Chassis

The internal frame of the lock.

Deadbolt lock

A lock having a bolt whose end protrudes from and retracts into, the lock front. When the door is closed and the deadbolt thrown, the deadbolt extends into a hole provided in the strike, locks the door, and does not retract when pressure is applied to the end.

Drive-in deadbolt

A deadbolt that is installed by hammering it into the edge of the door.

Hand of door

The swing direction of the door as viewed from the outside of the door. A right-handed (RH) door is hinged on the right and swings inward. A left-handed (LH) door is hinged on the left and swings inward. If either of these doors swing outward, it becomes a right-hand reverse bevel (RHRB) door, or a left-hand reverse bevel (LHRB) door, respectively.

Spindle

A bar that projects from the back of a cylinder that engages the lock mechanism. When the spindle is rotated by the key or thumbturn, it either locks or unlocks the lock. Also called “tailpiece.”

8T Deadbolt Service Manual 5–1

Glossary

Strike

A plate fastened to the door frame that the bolt projects into.

Strike box

A housing used in back of a strike to enclose the bolt or bolt openings.

Thumbturn

The component that projects or retracts a deadbolt operated by grasping and turning. Also called “turn knob” or “turnpiece.”

Tubular

The shape (tube-like) of the lock chassis and bolt enclosure.
