A door stop is the thin strip of moulding that runs around the inside of a door frame. The door closes against it, which keeps the door sitting flush in the frame and covers the gap between the door edge and the frame.

The Eased Two Edges profile has a flat face with two softly rounded edges, 3/8 in x 1-1/8 in. Made from primed white MDF (medium density fibreboard, a smooth engineered wood) and ready to paint. Sold in 14 ft lengths.

How much do you need? A standard door frame takes about 17 ft of door stop: one length for each side and one across the top. Two 14 ft lengths cover one door with plenty left over.
