Review on 4-Pack 1.5 Inch Swivel Stem Casters - 330 Lbs Capacity, Non-Marking Polyurethane Wheels & 3/8"- 16 X 1" Threaded Stems With Nuts For Furniture Carts Trolleys. by Eric Montgomery

I added these to a patio furniture table that I bought separately. I drilled into the legs and installed these regardless of the instructions. The table and these do not support the weight of a human - but that was more of the table and joinings than the wheels! Otherwise it’s been excellent. Great for the price.
