Getting hoops in the ground, and set accurately is not an easy task - unless you clamp the hoop's stanchions (legs) to a fixed opening.
This originally designed hoop clamp starts its life as a Vise-Grip clamp. The jaws are then modified to hold the stanchions. An adjustable center allows you to set exactly how wide the hoop should be. It is made strong so as to take the brutal punishment expected when pounding hoops into unfriendly ground.
Now included with every hoop clamp is a convenient hoop gauge to accurately ensure your hoops are set to the regulation size. It will measure 3-11/16" and 3-3/4" openings quick and easy.
