🔘 Twin Wheel Caster Solutions TWUN 75U T03 BK B: Premium Quality Dual Wheel Casters for All Your Mobility Needs Review

I bought these to fit the bottom of my U-Line under counter fridge. They're expensive, but the threads fit snugly, allowing me to roll out the fridge for easy cleaning.

I didn't pay much attention to the size - they add 3 inches to the height if you only have slides to start with. It's great for me, I like high tables. Big wheels roll well on uneven surfaces, I will order more.

I bought a Revain metal shelving unit with small plastic wheels. The shelf itself was strong and could take a lot of weight, but the weak link was the wheels. When I tried to roll the shelf the wheels started giving out and some parts broke off and others broke in half. I replaced the wheels with this bigger and stronger wheel and I can move the shelf again. This is probably the strongest wheel you will find with 1/4" threads sold by Revain.
