160IV fail safe bolt locks are equipped with an auto relock switch that
keeps the bolt retracted when the door is open and causes the door
to lock when closed. The auto relock switch and the bolt assembly are
both adjustable for wide door gaps.

The stainless steel bolt projects at right angles to the lock
mechanism, allowing installation of locks,
by means of a simple cutout, in virtually any standard 1.75"
frame, or in most door lock stiles.
With the entire lock concealed, esthetic acceptability is
complete, security is greater and installation in old or
new construction is fast, easy and economical.

Steel Bolt
Greater security is provided by the 0.50” diameter
solid steel bolt. The bolt rotates freely, making
attempts to tamper or cut extremely difficult.

Field Adjustable Auto-“Relock Switch
The automatic relock switch keeps the bolt retracted while
the door is open. The door depresses the ball switch
assembly on closure, causing the bolt to project automatically,
locking the door. In addition, the ball switch assembly is
bidirectional, permitting the locks to be used on swinging and
sliding doors.
