The zipper tape features a strong adhesive backing that withstands high traffic and provides reliable performance. The durable Oxford canvas fabric surrounding the zipper enhances strength and longevity, making it suitable for various applications. Unlike single-sided alternatives, this zipper includes a double-sided design, allowing flexible access from either side of the barrier or film. The two-way zipper is designed for easy installation. Simply peel off the backing paper, attach the zipper to the plastic barrier, open the zipper, and cut a slit in the barrier with scissors or a knife to create a convenient entry and exit point. This self-adhesive zipper is versatile and can be used in both indoor and outdoor settings, including greenhouses, grow tents, plastic films, and dust barriers. Package includes 4 rolls, each 7 feet in length. The 7-foot length accommodates various height requirements, offering adaptability across different environments.
