Case

Fully stainless steel case and internal components. 1" x 6" x depth. (Depth varies by backset)

Function

A huge bolt of laminated stainless steel, nearly three inches long, activated by an uncomplicated pivot mechanism, has made this basic MS® Deadbolt 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 door and jamb is greater than it should be.

Bolt

5/8" x 1-3/8" x 2-7/8" with 1-3/8 throw. Eight ply laminated stainless steel. Center ply has Alumina-Ceramic core to defeat any hacksaw attack, including rod-type “super” hacksaws.

Strike

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

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.

Cylinder Cam

MS1950 Series locks are operable by any standard 1-5/32" diameter mortise cylinder with special MS® dimensioned cam. Cylinders with MS® cams can be readily obtained from most cylinder manufacturers. See catalog for cylinder make and trim ring information.

Options

For jambs too narrow to accept the long bolt, the MS1950-050 offers a shorter bolt with hook shape to provide equal security against door-prying attempts. Second and third point locking bolts are available for pairs of doors.  All use any make mortise cylinder and thus can be keyed into systems with other types of doors. “SCHOOLHOUSE” version, also available, is modified so that operation from inside is “unlock only.” This lock is handed and must be specified LH or RH. Specify Series SCH1950. Operation from inside, with standard Adams Rite 4066 Thumbturn or with 4550 Deadlock Lever.

Standard Package

Individually boxed with machine screws for mounting. Cylinders and/or thumbturn available at extra cost. Shipping weight: 1-1/2 lbs.
