VEVOR Caster Wheels, 5-inch Swivel Plate Casters, Set of 4, with Security A/B Locking No Noise PVC Wheels, Heavy Duty 450 lbs Load Capacity Per Caster, Non-Marking Wheels for Cart Furniture Workbench

Yes. The wheel lock does lock the wheel from turning and swiveling.

Yes it does. Best casters on the market for any money, let alone the prices they sell at. Very high quality and heavy duty

The swivel does not lock, only the wheels. I have a 300lb workbench sitting on these wheels and once locked, the weight keeps the swivel part from moving at all.
