MS1850SN-050 Series MS® Deadlock (ANSI Size)

Operation
360° turn of key or thumbturn throws or retracts the

accepts any standard 1-5/32" diameter mortise cylinder or
thumbturn from either or both sides. Cylinder must have
MS® dimensioned cam.

• 1-1/2" only.

GRADE 1
E8281/E8291

The ANSI size MS1850SN-050 Deadlock utilizes a
laminated stainless steel hookbolt, activated by a pivot
mechanism to provide maximum security for wood or
hollow metal doors.

Case
• Steel with corrosion-resistant plating, measures 1" x 6" x 2-1/4".

Bolt
• 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.

Faceplate

Function

• Measures 1-1/4" x 8".

For hollow metal or wood sliding doors prepared for hardware according
to the specifications of the American National Standards Institute (ANSI),
this MS deadlock provides maximum security and ease of installation. Its
standard 1-1/2" backset dimension provides adequate clearance for the
deep jamb “pocket” of many commercial and industrial entrances. Also
useful for swinging doors closing against jambs too shallow for the 1-3/8"
throw of the MS1850SN swinging door deadlock.

Strike
• See back of page for dimensions of strike slot which can be
cut in metal jamb. Trim plate, box strike, and armored strike
are also available.

Cylinder Cam
• MS1850SN-050 Deadlocks 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
