This zinc alloy door stopper wedge slides under a door in seconds, holding it firmly open without tools or hardware to install. Sized at 4.7 x 1.57 x 1.24 inches, it fits door-to-floor gaps between 0.43 and 1.22 inches, so measure your gap before ordering for the best fit. The zinc alloy body resists rust and holds its shape over time, while textured PVC pads on the top and bottom improve grip on carpet, tile, laminate, and hardwood floors and keep the wedge from sliding once set. A built-in finger guard helps keep hands clear as the door swings. The set includes two wedges plus two self-adhesive wall bumpers that peel and stick to absorb impact and protect walls or door handles from dings. At just 0.51 lbs for the pair, it is light enough to carry from door to door around the house, office, or garage whenever you need to prop a door open or keep it from banging shut.
