National Mfg N343-111 Bypass Door Hardware Set 48 Inches

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N343-111 is a 48-inch bypass door hardware set designed for residential interior door installations. The set supports doors ranging from 3/4 inch to 1-3/8 inches in thickness and includes a steel track with a decorative finish. Wheels are maintenance-free and require no lubrication. The track system is engineered to prevent doors from accidentally jumping the track during normal operation. Carpenters and finish contractors install this hardware as part of closet, utility, or room-divider door systems.

This hardware set is suited for standard bypass sliding door configurations in residential applications. It is typically installed on closet openings or interior passages where space constraints make swinging doors impractical.
