PINDIA DC1700802PC2 Set of 2Pc Non-Slip Rubber Stackable Door Stopper Door Block Wedge/Door Jammer Guard Floor Mounted Door Stopper  (White)

This is a set of 2 wedge door stoppers. These stoppers can be inserted between the bottom of the door and the floor which jams the door in place. These stoppers can be used to stop doors with up to 0.7 inch clearance. Use them to stop metal as well as wooden doors. Since these stoppers are stackable, you can fasten one stopper on top of the other. This allows you to jam doors which have bigger clearance. So if the gap between the door's bottom and the floor is bigger, just stack two stoppers together and insert it beneath the door. The non-slip design helps keep the stopper firmly in place. In addition to this if your furniture is wobbling or shaking, these wedges can be inserted underneath the furniture to stabilize it.
