The National Hardware folding door bottom pivot is a compact, zinc-plated plastic/steel component designed to anchor and guide bi-fold or folding doors at the floor level. It mounts on the surface of a floor or door jamb and supports smooth, reliable movement of door panels. Built from cold-rolled steel with a durable nylon/ plastic base, this pivot resists corrosion and wear, making it suitable for everyday home or light-duty commercial use.
