FOOTMASTER GDR-60S-BLK Nylon Wheel and NBR Pad Ratcheting Leveling Caster, 550 lbs, Stem Mounted with 0.472" Mounting Hole Diameter, Black

So yeah they are expensive.But there was not other alternative for retrofitting refrigerator with wheels that would not scratch floor when moved. Some want longer stem. The stems are removeable. They unscrew. You can buy longer screws third party. Pick your own size. Internal Hex Allen Head Socket Set Screw

I'm using these on a table saw station. They work really well. I subtracted a star as one of the 6 I ordered had a sticky ratchet. It cleared up with a bit of use.

Returning. Yea, the picture shows one, but nowhere does the description say you only get one caster. Really? Everyone else sells them by the set and you only sell one for the same price? You honestly think I’m going to pay $200 for a set of casters?! They better hold up my planer AND build me a table for that much money!

Genuine Footmaster product used on a 900lb piece of custom equipment that is 3' W x 6' L for rolling around and leveling on concrete floor. Ratchet mechanism is well designed, functions properly, and in my opinion a necessity if you plan to move frequently. Wheels are small and hard, so only for continuous smooth (max brushed concrete) clean floors.

Worked as advertised. Would have liked the bolts a little longer to mount on 4x4 base
