The 1877-628 from Adams Rite is a Cylinder-Operated Flushbolt with Armored Faceplate for Wood Doors in Clear. The 1877-628 series Flushbolt is specifically designed for greater key control to prevent accidental locking of the inactive leaf of paired wood doors by children or other unauthorized persons. It uses the same basic over-center action mechanism as MS pivoted bolt deadlocks, recommended for installation at both the top and bottom of the inactive door with MS1850S Deadlock in the active door for maximum security. The 360-degree turn of the key throws or retracts the hex-section bolt, allowing the key to be removed only when the bolt is in a positively locked or unlocked position. It may be installed to lock at the threshold or at the header.
