Place the strap around the rider's back with the padded back support against the lower back and both "ends" of the strap resting on either side of the rider and the horse.
Allow the ends of the strap to hang over the rider's thighs on both sides. Place the metal safety release buckle face-up on the rider's right thigh.
Attach the right swivel snap hook of the strap to the small D-ring on the saddle.
Place the rider's right wrist through the wrist strap loop. There are two snap options for adjustment. The smaller adjustment is appropriate for most riders, and another if you have larger hands or are wearing aheavy winter jacket or gloves
Allow the strap to run down and hang along the inside of the rider's thigh (it will turn).
From the other side, reach under the horse and attach the straps together using the D-rings. Tighten snugly. Use the keeper to hold any excess strapping.
Attach the left swivel snap hook of the strap to the small D-ring on the saddle.
Take the long strap under the horse, over the girth, (be sure no pinching occurs) and run the small rectangle buckle through the large one hanging down from the left side of the saddle.
