Don-jo 1550SL Offset Flush Bolt Aluminum Silver Coated

Product Description

The DON-JO 1550SL is a 1/8-inch offset aluminum flush bolt designed for use on inactive door leafs in paired-door applications. Flush bolts secure the inactive door panel to the frame at the top or bottom, keeping the door aligned and latched until the active leaf is operated. This unit features a silver coated finish and is constructed from aluminum, making it lightweight without sacrificing structural reliability. It measures 11 inches in length and 2 inches in width, fitting standard door edge preparations. Installation is typically handled by door hardware installers, locksmiths, or finish carpenters during new construction or retrofit work.

The 1550SL is suited for commercial and residential door applications where a flush bolt is required on a paired door or French door setup. The 1/8-inch offset accommodates door edge conditions where a direct in-line mount is not practical. The silver coated finish provides a neutral appearance that blends with common door hardware finishes. Each unit is sold individually and is packaged four per case.

Installation Notes

Installation is performed by a qualified door hardware technician, locksmith, or finish carpenter. Ensure the door is fully supported and the inactive leaf is held stationary before drilling or mortising for the bolt housing. Follow the door manufacturer's template dimensions and verify that the strike or floor cup alignment is confirmed before final fastening. Refer to applicable local building codes for hardware requirements on rated door assemblies.
