I shopuld have bought this years ago!. Easy to use,a nd will quickly fasten to any 15mm rod. It has a stud to prevent the shoe from sliding all the way through, which I find frustrating on other products, and the handle will pull up-and disengage and turn around to position as needed. A very good accessory mounting block.
