Swivel Caster Wheels 600lbs,2 Inch Casters Set of 4, Heavy Duty Casters with Brake,Premium Dual Locking Castors with Plate for Cart, Furniture, Workbench, Trolley(16pcs Screws Included)

Good, reliable product.

Mounting position of holes is a little bit off I would like to see hole EITHER a little bit closer or a little bit farther apart. The holes are too wide for a 1.5 steel rail and too close to span the distance between the two.

Swivel, roll and lock very easy. When locked they are super stable (like feet).

I bought these for my heavy workbench and, boy, what a difference. These heavy-duty wheels are silky smooth and allow me to easily move my workbench around my garage. Ive only had them for two weeks and so far no flat spots have developed. Im going to purchase another set for my even heavier tool box.
