The SHY ZIP tracking system is a proven method of protecting specific areas against solar elements and pesky bugs. The system can withstand wind gusts of 40 - 60 miles per hour. Even when excessive pressure is applied to the fabric, the SHY ZIP remains tightly locked into the side trace for superior stability. The system is great for large windows, screen room enclosures, garage doors, patio covers and skylights. These can be both manually operated as well as motorized.
