The DELTANA 6FBS10B is a heavy-duty square flush bolt designed for use on double doors, French doors, and entry door pairs where one inactive door leaf must be secured to the frame or floor. The bolt mounts flush into the door edge, keeping the hardware concealed when not in use. At 6 inches in length and 0.75 inches in width, it delivers a solid mechanical lock point without protruding hardware that can interfere with door swing or clearance. The Oil Rubbed Bronze finish provides a dark, warm tone consistent with traditional and transitional architectural hardware schemes. Installation is handled by carpenters, finish hardware installers, or general contractors during door hardware trim-out.
This flush bolt is suited for residential and light commercial applications. It is commonly specified on the inactive leaf of double-entry door sets, interior French doors, and wood or MDF panel doors requiring a concealed top or bottom locking mechanism. The square profile aligns with square-cornered door hardware sets for a consistent look across a door assembly. It is sold as a single unit.
Designed as an OEM-style replacement or new-install flush bolt for double-door and French door assemblies requiring a concealed edge-mount locking mechanism.
Flush bolts are typically installed by finish carpenters or licensed door hardware installers during the trim-out phase of construction. A mortise or routed channel in the door edge is required to seat the bolt body flush with the surface. Ensure the door is unpainted and fully hung before marking and cutting the mortise to achieve proper alignment with the strike. Follow the door manufacturer's edge prep specifications and applicable local building codes for door hardware installation.
