This is a set of two 6" long polyester seat belt webbing Cinesaddle Fasty Straps designed to work with the Cinesaddle Stirrups or Anchors to secure your Cinesaddle to a moving or stationary platform. The Fasty Straps feature a buckle that allows you to secure the strap from loosening once you have cinched it tight.
You loop the Fasty strap around a Stirrup (not included) and put it under tension. Or when working with a Cinesaddle Anchor (not included), you can thread the end of the Anchor through the Fasty Strap's buckle to hold it fast.
