The MS1861 Series MS® Bottom Rail Deadbolt provides maximum security with MS deadbolt over-center/pivot locking mechanism. It utilizes hardened steel bolts for the limited space of ultra-narrow stile doors. Function: Using the same over-center/pivot locking mechanism as the basic MS® deadbolt, the MS1861 lies horizontally in the bottom rail of ultra-narrow stile doors which have insufficient vertical space for a lock, and 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. MS1861-02 locks either single-leaf or pairs of doors. Not recommended for wood doors. Operation 360° turn of key or thumbturn throws or retracts bolt(s). Key can be removed only when bolts are in a positively locked or unlocked position. Lock accepts any standard 1-5/32″ diameter mortise cylinder from either or both sides. Cylinder must have MS® dimensioned cam.
