The Invisible Door Stop (IDS) is one of the most revolutionary inventions in modern hardware history! This unique polymer-based product is simply attached to the door hinge and folds with the hinge when the door is opening and closing. This door stop allows for a wide range of settings to determine exactly where you want your door stop during the opening function. The best news.....the IDS is installed without drilling or attaching anything to your wall, floor or door casing. You keep the ambiance of your home while controlling the maximum opening of each door.
