Adams Rite MS1861 Series MS® Bottom Rail Deadbolt

Adams Rite MS Series has long been considered the industry standard and remains the dominant locking solution for narrow stile aluminum and glass doors. We offer a variety of shapes, features, and sizes to provide maximum security for sliding and swinging door applications.

MS1861 Bottom Rail Deadbolt provides maximum security with MS deadbolt locking mechanism. It utilizes hardened steel bolts for the limited space of ultra-narrow stile doors.

Adams Rite MS Series Function

The MS1861 lies horizontally in the bottom rail of ultra-narrow style doors which have insufficient vertical space for a lock, or tempered glass doors that have no style at all. The hardened steel cylindrical bolts allow simply 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 thumb turn projects or retracts bolt(s). The Key can be removed only when bolts are 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.
