MySit Heavy Duty 3 Inch Caster Wheels Set of 4 - 3/8"-16 x1-1/2" Threaded Stem Industrial Casters with Rubber Locking Brake | Replacement for Carts, Dolly, Workbench, Trolley | Perfect for Warehouse, Workshop & Home Garage Use

Initially when I purchased my Uplift desk, I did not get the rolling casters, which as it turns out was would have probably been the most useful upgrade to have done. These were half the price of the Uplift option and were available next day through Amazon. I made sure that they were the same diameter (M8), and they worked well. The stem was quite a bit longer than what the Uplift desk would take so I had to cut about a half inch off from each caster but otherwise I have zero complaints. I like the larger size than what comes with the standard uplift desk casters as it makes it easier to roll and maneuver when needed. Locking mechanism works well.
