MS1850S Deadlock with Deadlock Trim and Cylinder Bundle

Adams Rite MS1850S MS Deadlock 

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

Housing: Aluminum casting is 1-3/8" wide x 7-1/2" long x 1" deep.

Lever: 3" long aluminum with end-return design offers comfortable grip to lock or unlock.

Indicator: Words “LOCKED" in red letters or “OPEN" in black letters appear on white background when lock is thrown or retracted. Indicator is driven by lock bolt itself.

Stop Clearance: Lever housing projects 11/16" forward of cylinder backset centerline. Depending on height of door stop and width of door/jamb gap, it may be necessary to modify the stop to clear the housing. For fin type stops, this is easily accomplished. Hollow stops may preclude use of lever.
