This is the best solution I have found for putting new wheels back on the wagon. The slider rings were very flimsy and broke immediately, but these collars are strong enough and work great. The axle shaft was 5/8 inch. If you slightly loosen the screws on the clamp, the clamp becomes a little more than 5/8. Then mount it on the axle and tighten the screws and it's a very secure mount.
