The Glynn-Johnson FB41P-US26D Automatic Flush Bolt set is a commercial door control hardware assembly designed for the inactive leaf of a pair of wood doors. This automatic flush bolt pair helps secure the inactive door panel at the top and bottom without the need for manual operation each time the active leaf is opened or closed. This set includes both the top and bottom bolt assemblies, matching faceplates, guides, strikes, mounting hardware, and installation template. The unit is labeled FB41P-US26D and is intended for wood door applications in a US26D satin chrome finish. This type of hardware is commonly used in commercial, institutional, and light industrial openings where a clean, self-latching inactive door solution is required.

Detailed Description

This Glynn-Johnson FB41P-US26D set is intended for double-door openings where one leaf remains inactive until needed. In normal operation, the automatic flush bolt mechanism allows the inactive door to be secured at the frame and floor or threshold while coordinating with the active door system. When properly installed, the bolts retract and project automatically as the door assembly operates, which makes this hardware especially useful in commercial openings that require both convenience and secure latching. The components suggest this is a fairly complete open-box set with original hardware packs, trim plates, guides, and instructions. The visible finish and labeling support identification as a satin chrome version for wood door installations.

Installation Notes

Based on the visible instruction sheet, this set uses a top and bottom bolt arrangement with guides, strikes, and rub plates. Proper installation depends on door and frame preparation. Before purchase or installation, it is important to confirm:

• Door thickness
