This set comes with four casters that swivel and have brakes. They roll smoothly and lock securely. Lock features is nice, easy to lock and unlock though i wouldn't recommend using barefoot to do it.

Metal isn't flimsy, and bearings feel good. Rubber wheels are soft enough to not make noise or damage my house floor, and with a good texture to have a good grip on the floor. I think this softer outer will help avoid potential harm to softer surfaces...  Read More

These are way nicer than the casters at the box stores. They are fair priced and have a decent weight range. Great for a garage workshop and then some.

The brake on these holds tight avoiding expensive disaster too. They have more than adequate dust and debris protection around the swivel and hubs.

They are sturdy and heavy in the hand. They not only are very sturdy but also glide along the floor effortlessly!

Keep expectation low. These are not ball bearing smooth sliders. Bearings are sticky.
