Professional Manual Flush Bolt Solution for Double Door Applications

The Ives FB458 Single Manual Flush Bolt provides secure anchoring for inactive doors in double door configurations. Featuring a 1/2" diameter bolt tip with 3/4" throw and 7/8" vertical adjustment, this non-handed flush bolt is specifically designed for metal door applications. The round bolt head requires only a punched hole for simplified installation, while the special guide design and flat-sided bolt tip prevent bolt rotation during operation.

    A Handy Door Flush Bolt

    Posted by Jackson on Sep 15th 2023

    I recently bought the Ives FB458 Top or Bottom Manual Flush Bolt from zensupply.com. It's easy to install and works like a charm to secure my doors. The only drawback is that it could have clearer installation instructions. Overall, it's a handy addition to enhance door security.
