SIMPLE TO OPERATE & CONVENIENT TO STORE: This door stopper simply needs to be positioned at the bottom, with no need for drilling or screws. Just slide the wedge under the door, use your foot to secure the doorstop, and pull the door open with your hand until the wedge is firmly in place -- installation is done. The doorstop comes with adhesive mounts, making it easy to tuck away behind the door when not in use, reducing the chance of misplacing it. The wedges enable you to move around without the hassle of constantly opening and closing the door.
