MS1950-050 SERIES DEADLOCK
ALUMINUM
GRADE 1
E8281/E8291
The stainless steel MS1950-050 Deadlock utilizes a
laminated stainless steel hookbolt, activated by a pivot
mechanism to provide maximum security for a single leaf
narrow stile door.
Function
The MS1950-050 Deadlock answers the security need of sliding doors in
commercial, industrial, and institutional buildings. The mechanism is identical to
the widely used Maximum Security swinging door lock, except that the massive
laminated bolt is provided in a hook shape to resist the parting motion of sliding
door and jamb. The over-center MS locking action assures that forced entry
attempts to pry the door in any direction, up, down, or sideways, will be defeated.
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:
