Review on FOOTMASTER GDR 80F BLK Ratcheting Leveling Caster: The Ultimate Mobility and Stability Solution by Rodney Gonzalez

I put them under my new welding table I just built. And I would buy them again in a heartbeat. The most important thing for me was the leveling feature, since my shop isn't perfectly level, the most annoying thing is a wobbly table when I'm trying to build something. So the customization is excellent, and an added bonus are the rubber feet that reduce vibration. In the past I've made alignment systems using nuts and bolts, but when I found them I was hooked. The ratchet system for lifting and lowering is great. My desk weighs around 1200-1500 lbs + everything I build on it weighs 1000-1500 lbs and it wobbles up and down slightly under load. They're expensive, but definitely worth it.
