The MS1851S-210-335 from Adams Rite is a deadlock with straight bolt and 31/32" backset in black anodized. The MS1851S series Deadlocks utilizes a laminated stainless steel bolt which is activated by a pivot mechanism to provide the maximum security for a single leaf narrow stile door such that even a very tall and flexible one or an installation where the gap between the door and jamb is greater than it should be. It operates in such a way that the 360 degree turn of key or thumbturn throws or retracts the counterbalanced bolt and the key can be removed only when bolt is in a positively locked or unlocked position. The lock accepts any standard 1-5/32" diameter mortise cylinder or thumbturn from either or both sides. The cylinder must have MS dimensioned cam.
