National Marker N331140 Spring Door Stop Satin Nickel

Product Description

The NATIONAL MARKER N331140 is a satin nickel spring door stop sold in a 2-count pack. It mounts at the base of a door to prevent the door from swinging into and damaging walls, baseboards, or trim. The wide base plate provides stable spring support, reducing flex and wobble during contact. The base plate detaches from the spring for simplified installation. The flexible spring design absorbs impact and makes cleaning around the stop straightforward. This hardware is a standard residential and light commercial accessory installed by general contractors, maintenance technicians, and experienced DIYers.

The N331140 is suited for interior residential and light commercial door applications where wall protection is needed. The satin nickel finish coordinates with common door hardware finishes. The detachable base plate design allows the spring to be removed independently, which simplifies both initial installation and future maintenance. Sold as a 2-count pack, making it practical for multi-door installations in a single purchase.
