Don-jo 1551SL Flush Bolt 1/4 Inch Offset Aluminum

Product Description

The DON-JO 1551SL is a 1/4 inch offset aluminum flush bolt designed for use on inactive door leafs in paired-door assemblies. It mounts to the face of the door stile and engages a strike in the frame head or threshold to hold the inactive leaf in position. The aluminum construction keeps weight low while providing the rigidity required for consistent latching. The silver coated finish blends with standard aluminum door hardware. Door hardware installers and locksmiths are the typical trade professionals who specify and install this bolt.

This flush bolt is suited for aluminum or hollow metal door pairs in commercial and light commercial applications where the inactive leaf must be held secure when the active leaf is in use. The 1/4 inch offset mount accommodates door edge conditions where a flat-mount bolt does not align properly with the strike centerline. It is sold as an individual unit and is appropriate for both new door installations and replacement of worn or damaged existing flush bolts.

Key Features

• 1/4 inch offset mount accommodates door edge clearance requirements
• Aluminum construction reduces overall door hardware weight
• Silver coated finish coordinates with standard aluminum door and frame hardware
• 10.75 inch body length provides substantial engagement travel for inactive leaf hold

Compatibility

Installation Notes

Installation is performed by a qualified door hardware installer or locksmith. Ensure the inactive leaf is properly aligned and the door frame strike location is marked before drilling. Verify that the offset dimension matches the existing or planned strike centerline before mounting. Follow applicable building and fire code requirements when installing flush bolts on rated door assemblies.
