These wheels worked great for the project my son was doing. He made a cart to hold a old scout body on so he could roll it anywhere in the shop it was needed, worked so good will be looking at buying more sets for future projects the weight rating is beyond what this project needs, he originally bought the HF air filled dolley wheels then had to replace the air filled wheels on the casters to solid because the center hubs folded up during turning then started to replace those with solid ones and bushings when I ran across these and decided to give them a try with a little modification to his original mounting pads these work great. Have not tried to roll across gravel lot yet but would probably work as long as its been dry for awhile, hopefully this gives others ideas for uses of these casters besides a scaffold. Not sure if pictures are going to post tried 5 different times
