Adams Rite Bottom Rail Deadbolt

Use on commercial ultra-narrow stile or tempered glass doors whose bottom rail is too shallow for an Adams Rite MS1861. Mechanism is that of the MS1850A deadbolt, but with the bolt size reduced to allow proper operation in the threshold. This keeps the threshold strike opening to a minimum to avoid collection of debris or snagging of spike-heeled shoes. Armor faceplate protects cylinder set screws from tampering and keeps them from loosening.

Bolt is 15/32" x 5/8" x 2-1/8" with a 5/8" throw using 6 ply laminated steel with 8 plys in the case. Center ply has Alumina-Ceramic core to deter hacksaw attacks. Case is made of steel with corrosion-resistant plating. 31/32" backset: 1" W x 6" L x 1.63" D. 1-1/8" backset: 1" W x 6" L x 1.78" D.

Operation: A 360° turn of key or thumbturn (cylinders not included) throws or retracts the counterbalanced bolt. Key can be removed only when bolt is in a positively locked or unlocked position. Accepts standard 1-5/32" diameter mortise cylinder from either or both sides using an Adams Rite MS cam.

Optional strike sold separately and available special order only.

31/32" and 1-1/8" backset models available. Clear Anodized Aluminum Finish only.
