The IVES FB45810B is a manual flush bolt designed for installation on metal doors. Flush bolts mount into the edge of a door to provide a concealed locking point at the top or bottom of an inactive door leaf, keeping the door aligned and secured without exposed hardware. This unit ships in an oil rubbed bronze finish and measures approximately 11.8 inches in length with a 1.5-inch width and height profile, weighing 0.7 pounds. It is installed by licensed carpenters, door hardware specialists, or commercial locksmiths as part of a paired or double-door assembly.
The FB45810B is suited for commercial and residential metal door applications where a clean, low-profile locking solution is required on an inactive door leaf. Typical installations include double-entry doors, storage room pairs, and vestibule assemblies where one door must remain stationary while the active leaf operates freely. The oil rubbed bronze finish coordinates with matching lever trim, hinges, and other door accessories in the same architectural finish family.
Designed as an OEM-style replacement or new-installation flush bolt for metal doors requiring a manual edge-mount locking mechanism on an inactive door leaf.
Installation of flush bolts on metal doors typically requires a licensed door hardware technician or commercial locksmith with appropriate routing or milling tools to prepare the door edge mortise. Power down or disengage any electric latch or access control hardware on the door assembly before beginning work. Follow applicable building codes and door manufacturer specifications for edge preparation dimensions to ensure proper bolt throw and strike alignment. Do not over-tighten mounting fasteners on hollow metal door edges, as this may deform the door stile.
