Adams Rite 1830-Bottom Rail Deadlock (Swingbolt), 31/32", or 1-1/8" cylinder height

The Adams Rite 1830 Bottom Rail Deadlock provides bottom rail locking in ultra-narrow stile aluminum or tempered glass doors. Tamper-proof with an armored faceplate, it protects with a minimum threshold strike opening.


For bottom rail locking of ultra-narrow stile or tempered glass doors whose bottom rail (shoe) is too shallow for the MS1861 Bottom Rail Deadbolt.
