What is FSR?
Fabric Stress Reinforcement (FSR)
FSR®- Fabric Stress Reinforcement
FSR is the long term solution for a long life cover.
FSR is a 2” wide, 1000 pound test webbing sewn on the inside of the roof.
FSR provides the necessary support to the fabric to offset the added weight caused by wind, rain, snow, ice and gravity. It also helps support the continual weight of the side fabric.
