Adams Rite 1870 Cylinder Operated Flushbolt

Designed for greater key control, the 1870 Cylinder- Operated Flushbolt for aluminum stile doors prevents accidental locking of the inactive leaf of paired doors. 

Function

Designed for use instead of conventional flip-lever operated flushbolts, the 1870 Cylinder-Operated Flushbolt gives building management key control of the inactive leaf of paired doors. Prevents casual locking of the inactive leaf by children or other unauthorized persons. Uses same basic over-center action mechanism as MS® pivoted bolt deadlocks. Recommended for installation at both top and bottom of inactive door with MS1850S Deadlock in active door for greatest security. May be installed to lock at threshold or at header. 

Operation

360° turn of key throws or retracts the hex-section bolt. Key can be removed only when bolt is in a positively locked or unlocked position. Accepts any standard 1-5/32" mortise cylinder from either or both sides. Cylinder must have MS® dimensioned cam (see CYLINDERS).
