AdamsRite - MS1850A - Deadbolt 1-1/8 Backset - Hookbolt - Flat Faceplate - Dark Bronze Anodized

The MS1850A-3-50-313 series Deadlocks utilize 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 the key or thumb-turn throws or retracts the counterbalanced bolt and the key can be removed only when the 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 an MS-dimensioned cam.
