Ives Flush Bolts

Key Features

• Recessed flush‑mount design that installs in the door edge to keep hardware concealed and reduce projection hazards.​
• Constant latching and manual models to suit fire‑rated pairs, high‑traffic openings, and standard commercial doors.
• Options for wood doors and hollow metal doors, including dedicated models with appropriate fire listings and hardware geometry.
• Standard rod lengths (often 12") and 3/4" bolt throw on many models, providing positive engagement into the frame or threshold.
• Broad finish selection, such as Satin Stainless Steel (US32D/630) and Satin Brass (US4/606) to coordinate with surrounding door hardware.

Key Benefits

• Enhanced security for double doors by locking the inactive leaf at the top and/or bottom, preventing unauthorized or uncontrolled opening.
• Code and fire‑door compliance when using constant latching or listed manual bolts on labeled pairs, helping maintain proper door sealing and latching.
• Clean, unobtrusive appearance that preserves the door’s design, ideal for corridors, lobbies, and architectural interiors.
• Durable, long‑service hardware built from commercial‑grade materials for repeated cycling in schools, healthcare, and office environments.
• Easy operation with smooth bolt mechanisms that staff can quickly throw or retract when the inactive leaf needs to be used.

Applications

• Commercial corridors and stairwells with double egress or paired doors where the inactive leaf must stay secure most of the time.​
• Fire‑rated wood and metal door pairs in schools, hospitals, and offices where constant latching or listed flush bolts are required.
• Conference rooms, lobbies, and worship spaces that use double doors and need a concealed, easy‑to‑use method to secure one leaf.​
• Multifamily and hospitality properties where aesthetics and reliable security are both priorities.
