Height‑adjustable door stop with threaded foot

A compact, height‑adjustable door stop aimed at fitting imperfect, old or non‑standard doors more precisely. It uses a threaded “support foot” that lets you fine‑tune the contact point and lock it in place at three distinct working heights: 20 mm, 30 mm and 40 mm. Three fixed heights: 20 mm, 30 mm and 40 mm for flexible setup on different doors. Threaded foot works like a support jack, allowing fine adjustment to match uneven, warped or old door bottoms more accurately. Compact cylindrical body sits under the door edge and provides a stable, non‑slip stop once adjusted. Ideal for retrofits where standard door stops don’t reach or where the floor and door have irregular clearances.
