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. 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.
