National Mfg N343-087 By-pass Door Hardware Kit 72in

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N343-087 is a 72-inch by-pass door hardware kit designed for sliding interior door installations. This kit provides the track, hangers, and guide hardware needed to mount and operate two by-pass doors on a shared rail system. The steel track features a decorative finish and includes a dial-action hanger system that allows vertical door adjustment without detaching the hangers. Wheels are maintenance-free and require no lubrication. The door guide ensures smooth, controlled door movement throughout the full travel of the track. This kit is installed by finish carpenters, general contractors, and experienced DIYers during interior door rough-in or renovation work.

This hardware kit is suited for residential closet, pantry, and room-divider by-pass door applications requiring a 72-inch track span. It supports door configurations where two panels slide past one another on a common steel rail. The dial-action hanger system simplifies door hanging and removal, making it practical for installations where doors may need to be taken down for access or rehanging during flooring or trim work. The kit ships as a single package containing three components. No lubrication schedule is required after installation, reducing long-term maintenance demands.
