The DELTANA 4FBS15 is a heavy-duty flush bolt designed for door hardware applications where a clean, surface-flush installation is required. Measuring 4 inches in length, 1.25 inches in width, and 0.75 inches in height, this flush bolt installs into the door edge or face to keep inactive doors secured without exposed surface hardware. The satin nickel finish provides a consistent, low-sheen appearance suited to commercial and residential door hardware installations. At 0.2 pounds, the unit is compact and straightforward to handle during installation.
This flush bolt is suited for residential and light commercial door applications where paired or inactive door panels require a reliable latching point. It is typically installed on the inactive leaf of a double door set, securing that panel to the frame at the top, bottom, or both. The heavy-duty construction makes it appropriate for both interior and exterior door applications where a durable, low-profile bolt is specified.
Designed as an OEM-style replacement or new-installation flush bolt for standard residential and light commercial door assemblies requiring a heavy-duty, flush-mount latching solution.
Flush bolts are typically installed by finish carpenters, door hardware installers, or licensed contractors working on door assemblies. Before installation, ensure the door is properly hung and the inactive leaf is square in the frame. Mortise or bore the door edge as required by the bolt body dimensions prior to fastening. Follow all applicable local building codes regarding door hardware requirements for egress and accessibility.
