ZipWall HDAZ2 3 in. x 84 in. Heavy-Duty Adhesive Zippers Includes Knife (2-Pack)

ZipWall Self-Adhesive Zippers allow you to quickly create a doorway in plastic dust barriers, providing easy entry and exit. Simply remove the paper backing and stick the zipper to the plastic barrier. Then open the zipper and cut the plastic to make a door. Heavy-duty zippers have a greater adhesive area that allows for an aggressive tack. Their 3 in. wide all-cloth construction provides maximum durability, making them ideal for high-traffic areas. Both Heavy-Duty Zipper packages come with a special Zipper Knife sheeting cutter that cuts a wide opening so the zipper teeth will never jam. All ZipWall zippers come with flap hooks that easily hold a door flap open.
