Door Handle Latch Mechanism. Door latches join the two surfaces together and then secures them in place using a strike plate on the opposite side. While most latch mechanisms use a retracting tubular latch mechanism that goes in when the handle is turned some doors like closets use a ball latch. The door handle has only a lever handle or knob which operates this latch.
The bolting mechanism has a spindle that retracts from the door frame when one of the handles is twisted allowing the door to open. An improperly functioning latch may be the result of a poorly fitting door.
The lock mechanism may not work simply because the lock is dirty or dry and needs to be lubricated with graphite do not use any type of oil because this will gum up the works.
The bolting mechanism has a spindle that retracts from the door frame when one of the handles is twisted allowing the door to open. Smaller than other variations of locks meaning these tubular latches can be fitted with much less effort and minimal cutting and drilling of the door. The service kit is for keyed entry door latches and provides square and round face plates in polished brass and a drive in collar. Perhaps the most important of all door handle parts is the latch mechanism.
