Leveling Casters Set of 4, Heavy Duty Workbench Stem Caster Wheels with T-Nuts, Adjustable Retractable Industrial Castors,for Machine, Equipment Load 2200 Lbs (Stem Size 1/2" and M12)

These are superb! Sturdy and stable. I deployed them in a wood lathe weighing about 500 pounds. They are very easy to lower and raise. It takes about 30 seconds per wheel. I cut the end off an old Phillips head screwdriver (1/4” diameter) to serve as a Tommy bar (lever handle).

These appear to be well made and easy to adjust. If you need longer stems than what they provide, you can use 12mm or 14mm threaded rod to make whatever length is required for your application.

It was done very well.

These are great. Now I can move our shop table easily and level the table out!!

These work great. Be careful how far the stud threads into the caster. Too deep and it will jam the ratcheting mechanism.

These are nice additions to a work surface. The cord is way too long an 18 - 24 inch cord length option for under desk power strip use would be great!

Very well built ! Works great!

These are nothing but junk. Doesn't crank up or down with any weight on the table at all. Two of them wouldn't crank up or down at all. Sent them back for a refund.
