Review on 🔒 Locking Casters with M8 1.25×25mm Threaded Capacity - High-quality Mobility Solutions by Ken Lawson

This does the job. I looked for wheels that weren't soft rubber and they were. I replaced wheels on a car chain that came with the product and was removed after a few years of use. These wheels look like stronger threads and smoother ball bearings so should last longer. They even come with hardware if you need it, but I didn't have any spares.
