Adams Rite Manufacturing MS1861-02-603 Bottom Rail Two Point Deadlock, 603/US2G Zinc Plated offers unparalleled security for ultra-narrow stile doors, including tempered glass installations. This robust deadlock features an advanced MS deadbolt over-center/pivot locking mechanism that ensures maximum protection. Its design is specifically tailored for spaces where vertical locking mechanisms are impractical, making it ideal for applications with limited space. Constructed from steel with a corrosion-resistant plate, the case measures 1" x 6" x 1-13/16", providing durability and longevity. The deadlock boasts hardened steel bolts: a stainless steel vertical threshold bolt with a 13/16" throw and a hardened steel horizontal bolt with a 1-1/8" throw. For installation, 7/16" drilled holes are required in metal thresholds, and a plate must be provided for wooden doors. The MS1861-02 allows for operation via a standard 1-5/32" diameter mortise cylinder, ensuring compatibility across various cylinder manufacturers. The lock is designed for single-leaf or pairs of doors, making it versatile for various entry configurations. The ability to convert from the MS1861-01 version to the MS1861-02 using the 4014 Conversion Kit adds to its functionality, making it a smart choice for professionals and knowledgeable homeowners seeking reliable security solutions.

Bottom Rail Two Point Deadlock, 603/US2G Zinc Plated

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.
