Zipscreen’s® hidden z-LOCK™ technology creates the perfect gap-free shade for the ultimate privacy and protection in your outdoor living area. The patented z-LOCK side-fastening technology offers a fabric guide like no other. Concealed within the channels, z-LOCK fastens the fabric securely to create a smooth and streamlined finish. Designed to completely seal and protect your outdoor area from the sun, wind, rain and pesky insects, Zipscreen exterior shades provide privacy and protection for year round use of your outdoor space. The z-LOCK side-tensioning system uses a one-of-a kind, Japanese-made zip, which fits perfectly into the slim side channels and stays hidden from view. Its teeth are made from durable, high quality polymer that won’t wear out over time, unlike low quality cord systems made from rubber or soft plastic that can easily weaken. Z-LOCK’s unique two-piece design provides up to 20mm side adjustment to fit in areas which may not be perfectly square. A seamless guided movement ensures the fabric won’t blow out and eliminates any rattle, even on breezy days, for a consistent, smooth operation every time. Zipscreen’s slim side channels and modern cassette are available in a range of colors to coordinate with your home's style. The hidden z-LOCK side fastening system stays out of sight to help maximize your view. Rollease Acmeda offers a comprehensive 5-year warranty on Zipscreen hardware. A Zipscreen shade seamlessly integrates your indoor and outdoor entertaining areas, providing the ultimate outdoor shade solution for your home.
