The Plissé is a retractable pleated fly screen door system that features a virtually non-existent bottom rail. The Plissé door pleated screen is not under spring tension, it is pulled and re-tracted with a double caterpillar chain, on the top and in the bottom. This allows it to stay in position when opening and closing with no pull-back traction. Plissé is a modular solution: multiple panels can be combined to cover large patio doors with different opening options. Suits all styles of hinged in-swing or out-swing doors and sliding glass doors.
