DEADLOCK
ALUMINUM
GRADE 1
E8211
The MS1850S Deadlock utilizes a laminated stainless steel
bolt, activated by a pivot mechanism to provide maximum
security for a single leaf narrow stile door.
Function
A huge bolt of laminated stainless steel, nearly three inches long, activated by an
uncomplicated pivot mechanism, has made this basic MS
®
Deadlock the standard
of the narrow stile door industry. The length of this bolt provides maximum
security for a single leaf door, even a very tall and flexible one or an installation
where the gap between the door and jamb is greater than it should be.
Operation
360° turn of key or thumbturn throws or retracts the counterbalanced bolt. Key
can be removed only when bolt is in a positively locked or unlocked position. Lock
accepts any standard 1-5/32" diameter mortise cylinder or thumbturn from either
or both sides. Cylinder must have MS
®
dimensioned cam.

Narrow stile doors require a trim ring to fill the gap remaining between the cylinder
shoulder and stile when a standard mortise cylinder is used. If the security of the
hardened steel Adams Rite MS4043 Cylinder Guard is not required, this ring may be
simply a length of 1.171 I.D. tubing. Its length varies depending on door thickness or
cylinder make and number of pins. The specific length required can be quickly
determined by the following formula:
