The 1870-30-313 from Adams Rite is a Standard Cylinder-Operated Flushbolt with Flat Faceplate in Dark Bronze. The 1870-30-313 series Flushbolt is specifically designed for greater key control specially for the aluminum stile doors that prevents accidental locking of the inactive leaf of paired doors. It uses same basic over-center action mechanism as MS pivoted bolt deadlocks. It is recommended for installation at both top and bottom of inactive door with MS1850S Deadlock in active door for greatest security. The 360 degree turn of key throws or retracts the hex-section bolt and the key can be removed only when bolt is in a positively locked or unlocked position. It may be installed to lock at threshold or at header.
