Review on Broad Brim 16-Inch Caster Socket by Firman Harrington

Sturdy design. The wheels fit snugly in the nests. I used heavy-duty 650-pound casters with quiet neoprene wheels, which were offered as a replacement for the typical hard plastic casters found on office chairs. It's nice to find a quality product these days. I used them for a revolving bookshelf that I built to be strong enough to support the weight of the wood structure and all of the books. Very happy.
