Adams Rite MS1861 Bottom Rail Deadbolt, Vertical Bolt, Zinc Plated

Product Overview

MS1861 bottom rail deadbolt provides maximum security with MS deadbolt locking mechanism. The MS1861 lies horizontally in the bottom rail of ultra-narrow stile doors which have insufficient vertical space for a lock, or tempered glass doors which have no stile at all. The hardened steel cylindrical bolts allow simple drilled strike holes of a relatively small size to minimize the nuisance and danger presented by some threshold strikes in collecting debris or snagging on high-heeled shoes. 360 degree turn of key or thumbturn projects or retracts the bolt. Key can be removed only when bolt is in a positively locked or unlocked position. Lock accepts any standard 1" (25.4 mm) length, 1-5/32" (29.4 mm) diameter mortise cylinder with MS cam such as the 4036 mortise cylinder or thumbturn such as the 4066 thumbturn, available separately. Lock accepts cylinder from either or both sides.
