From the original Cashel. Western Stirrup Position Adjusters - Made of top quality 1/8th inch hand polished aluminum (no rust) molded under 7,000 pounds of pressure, the E-Z Knee is placed between your existing Western stirrup and the saddle fender, keeping the stirrup set at a right angle to the horse.
