The 1870-30-313 from Adams Rite is a Standard Cylinder-Operated Flushbolt with Flat Faceplate in Dark Bronze. This flushbolt is specifically designed for greater key control, especially for aluminum stile doors, effectively preventing accidental locking of the inactive leaf of paired doors. Utilizing the same over-center action mechanism as MS pivoted bolt deadlocks, it offers reliable security. For optimal performance, it is recommended to install at both the top and bottom of the inactive door alongside an MS1850S Deadlock on the active door. The innovative design allows a 360-degree turn of the key to throw or retract the hex-section bolt, with the ability to remove the key only when the bolt is locked or unlocked. This versatile piece can be installed to lock at the threshold or header.
