Adjustable Height: First swing the door to the desired fixed angle, then simply place the rubber door stopper between the floor and the door, stack it to the desired height, no drilling or tape is required to secure the door opening and closing angle. Applicable Scenarios: Rubber door stops are suitable for all types of floors/door panels: hardwood floors, tiles or carpets/wooden doors, metal doors, glass doors, even very heavy doors. These door stops prevent the door from moving and have excellent gripping capabilities.
