HDAZ2 Zipper, Heavy-Duty, 7 ft L, 3 in W, Fabric

Zipwall® heavy-duty zippers are the quickest way to create an entry in a plastic dust barrier wherever you need it. Two Zipwall® zippers create a hands-free entry - simply roll up the flap and hold the door open using two flap hooks. This hands-free door can be as wide as needed to get equipment and supplies in and out of the worksite. Patented ZipperKnife™ sheeting cutter prevents jams. Specially designed to double-cut the plastic, the ZipperKnife™ leaves a clean cut that keeps plastic away from zipper teeth.
