The zipper tape with a strong adhesive backing withstands high traffic and is effective and strong. The high-quality Oxford canvas fabric surrounding the zipper enhances its durability, making it suitable for applications. Unlike one-sided alternatives, our zipper comes with a double-sided zip, providing flexibility in opening the door from either the inner side of the barrier or other films. Our two-way zipper is designed for easy and quick installation. Simply peel off the back paper, adhere the zipper to the plastic barrier, open the zipper, and use scissors or a knife to cut a slide on the barrier, creating a convenient door for easy entry and exit. The self-adhesive zipper is versatile and can be applied in settings, both indoors and outdoors. It is suitable for use in greenhouses, grow tents, films, and dust barriers. Comes with 4 packs, 7ft length per pack. With a length of 7 feet, the zipper accommodates different height requirements, making it adaptable to situations and environments.<br><br>Colour:Black Material:Nylon<br><br>Package Contents: 4 roll x Zipper Tape<br><br>Only the above package content, other products are not included.
