4 Inch Caster Wheels, Heavy Duty 4” Casters Set of 4 with Brake, TONSUM No Noise Polyurethane (PU) Wheels and Safety Dual Locking casters, Swivel Plate Castors(Two Hardware Kits for Free)

Used for a table in my shop that I wanted to move around, sturdy enough to support the table and stuff on it and very easy to move around and lock in place.

Work as they should.

So far so good.. I used these for a shop table build. They roll smooth and the locks hold good.. Locking tab could be a little longer for me but all in all Im happy with my purchase so far.

I like the wheels because you can lock and unlock them fairly easy.
