ZipWall HDAZ2 2Pk HD Adhesive Zippers 3" x 84" Includes Knife

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. Effective at temperatures as low as 32 degrees F. Tip: To improve the zippers’ adherence to a plastic barrier when working in cold temperatures, we recommend attaching them to the plastic ahead of time at a temperature of 50 degrees F or higher. Note: A single zipper may be used to create a fly-door. Contents: Two zippers, two flap hooks, and one ZipperKnife™ sheeting cutter.
