Most convenient: 3 groups of door stops are more convenient and flexible than traditional door stops. When the door stop is fixed on the floor, you only need to step on it. Then rise. The most stable: the bottom of the door stop has an anti-skid three-dimensional bending structure. The door stop will firmly grasp the floor, silent and anti-collision, to prevent damage to the wall. Most supported: Door stop can be used on all floor surfaces, whether ceramic tile, vinyl, concrete, carpet, glass or wood floor. This commercial door stop is applicable to markets, apartments, ordinary residences, solid interior doors, garages, metal doors and other places. The most flexible: there is an adjustment knob at the bottom of the rubber tip, so that the door stopper can firmly grasp the floor. You can control it at any angle of the door, and stop anywhere you want. Packaging: 3 sets of door stops
