any make mortise cylinder and thus can be keyed into
systems with other types of doors. “SCHOOLHOUSE”

from inside is “unlock only”. This lock is handed and

MS1950 SERIES DEADLOCK
ALUMINUM
GRADE 
E
The stainless steel MS1950 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:
