Adams Rite Flush Bolts

Key Features

• Cylinder‑operated function: A 360‑degree key turn throws or retracts the hex‑section stainless steel bolt for secure locking and unlocking.
• Positive key control: The key can only be removed in fully locked or fully unlocked positions, reducing the risk of partial engagement and door damage.
• Standard mortise cylinder compatibility: Accepts 1" length, 1‑5/32" diameter mortise cylinders with MS® cam or thumbturns, from one or both sides of the door.
• Optimized geometry for aluminum and hollow metal doors with typical 1‑1/4" backsets and standard cylinder heights for clean alignment with adjacent Adams Rite locks.
• Corrosion‑resistant steel cases and stainless steel bolts with approximately 11/16" throw for reliable engagement into headers, thresholds, or strikes.
• Architectural faceplate finishes such as aluminum (628) and Satin Chrome (626) that blend with typical storefront and commercial door hardware.

Key Benefits

• Greater key control on inactive leaves: Cylinder‑operated flush bolts allow facility managers to integrate inactive leaf locking into their master key system instead of using manual, locally operated bolts.
• Reduced accidental locking: Design and key‑removal logic help prevent partially thrown bolts that can damage frames or prevent proper door closing.
• Cleaner appearance and fewer snag points: Edge‑mounted flush bolts eliminate surface bolts on the door face, important for modern storefronts and glass systems.
• High security for paired openings: Stainless steel bolt construction and positive key operation enhance security at high‑risk exterior or perimeter entrances.
• Broad compatibility and flexibility: Adjustable cylinder heights and standard dimensions make these flushbolts easy to integrate into new or retrofit aluminum and metal door packages.

Applications

• Aluminum storefront pairs where the inactive leaf must be key‑controlled and visually clean, often matched with Adams Rite MS® locks on the active leaf.
• Hollow metal door pairs are used on commercial back‑of‑house, service corridors, and loading doors requiring secure inactive leaf locking.
• Glass and metal entrance systems in retail, office, and mixed‑use buildings are seeking integrated, low‑profile locking solutions.
• High‑security and access‑controlled openings where master key systems and strict bolt control are a priority.
