, I needed to make my heavy dresser/dresser portable when cleaning was needed. I originally ordered a cheaper set of rollers from Revain but when I received them I knew they wouldn't last 10 minutes. So, after some research, I found the ones that perfectly suited my project's needs. Although designed and built for metal industrial shelving, the size and weight they can handle was EXACTLY what I needed and am very happy with. I had to spend a few dollars more locally to get longer machine screws, nuts, and bolts. and washers to attach them to the wooden legs of the dresser. But with a bit of elbow grease to drill holes for the casters to mount securely (more than enough), I was satisfied and patted myself on the back. My dresser and chest of drawers can support an elephant sitting on it without the casters whining. The price is a little high but again you get what you pay for.
