Adams Rite 1877-313 Cylinder-Operated Flush Bolt

Adams Rite 1877-313 Cylinder Operated Flush Bolt delivers reliable security and functionality for aluminum stile doors. Designed to prevent accidental locking of the inactive leaf in paired door setups, this flush bolt is an essential component for both commercial and residential applications. Featuring a convenient 1-1/4" backset and a robust 13-1/2" cylinder height, the Adam Rite 1877-313 accommodates standard mortise cylinders with MS® cams, making it easy to integrate into your existing security systems. The durable stainless steel bolt, measuring 3/8" flat to flat with a 11/16" throw, ensures long-lasting performance, while the corrosion-resistant steel case measures 1" x 6" with variable depth based on the backset configuration. Installation is straightforward with included mounting screws and detailed instructions, although the rod/bolt assembly comes unattached for flexibility during setup. The faceplate measures 1" x 6-7/8", and a compatible strike for wood thresholds is available separately. Finished in a dark bronze anodized aluminum, the Adams Rite 1877-313 not only enhances security but also complements a variety of architectural styles, making it a perfect choice for any project.
