Review on Adjustable Capacity Workbench Leveling System by Dr. Luck by Calvin Chavva

Works well. Used it for my welding table (4ft x 8ft with 3/4" plate with 3x3 pipe) which weighs about 1300 pounds. I would recommend bolting the rollers instead of welding. The grease they use for the bearings use is heat sensitive (ask me how I know).The rubber is hard but that gives the table a little play when nothing is on it.As I put all my stuff on it it tightened even more.I Haven't tried rolling it but I think it rolls fine If you're looking for a fake rig this won't work unless you preload it with at least 1400lbs (including table weight) to compress the rubber .
