Specifications
CYLINDER BACKSET
• 31/32", 1-1/8", or 1-1/2".
CASE
• Steel with corrosion-resistant plating, measures 1" x 7-3/8" x
depth. Depth varies by backset (see table on back of page).
LATCHBOLT
• Zinc alloy with Delrin face for smooth, quiet action, measures
5/8" x 5/8" with 7/16" throw. Handing easily reversible. Bolt
can be held fully retracted to allow door to be free swinging
(see illustration on back of page).
LOCKBOLT
• 5/8" x 1-3/8" with 13/16" throw. Eight-ply laminated stainless
steel. Center ply has alumina-ceramic core to defeat any
hacksaw attack, including rod-type “super” hacksaws, while
hook shape repels pry bar attempts to “spread” the door from
its jamb or lift it off its track.
ARMORED STRIKE
• Satin stainless steel trimplate with steel mounting plate
and dust box. Flat strike furnished. Also available for pairs
of doors in radius shape, or flat with square corners for
ANSI hollow metal jambs. Flat strikes also available with
longer lip. MS+1890 Deadlock/Latch cannot be used with
electric strikes.
CYLINDER CAM
• MS+1890 Series locks are operable by any standard 1-5/32"
diameter mortise cylinder with MS
®
cam dimensioned as
shown. Cylinders with MS
®
cams can be readily obtained
from most cylinder manufacturers. See CYLINDERS section
for cylinder make, thumbturn and trim ring information.
OPTIONS

Handles/paddles on both sides solve, with minimum traffic
impediment, the problem of doors that stand ajar due to wind
or air-conditioning pressures.

for mounting. Cylinders available separately.
Shipping weight: 2 lbs.

deadlock for after hour and traffic control convenience
during business hours.
Function
Maximum Security deadlock after hours, plus traffic control convenience for

requiring three modes of door control: 1. Both lock and latch bolts retracted
for unrestricted entry and exit during business hours, 2. Handle-operated
latch for exit-only traffic just after closing and 3. Maximum Security hookbolt
for overnight lockup. NOTE: Handle or paddle operates latchbolt only.
Operation
360° turn of key or thumbturn throws or retracts the hook-shaped deadlock.
120° further turn retracts latch bolt as well. Cylinder may be any make standard
1-5/32" diameter mortise type with MS
®
dimensioned cam (see CYLINDERS).
Handle retracts spring-loaded latchbolt only.

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:
