Used them on some pedestals. They are great for the money.

Worked flawlessly. They seem to be very durable. Otherwise these are amazing to use and make moving the work benches so much easier.

This is much easier than trying to lift or lower each castor separately. With good shoes or boots, pulling them up by foot is just ok, but they work well. Nut-spacers you see are to maintain the vertical mounting plane.

The mounting template is accurate and easy to use. The install quite easily and work very well. My only complaint is kinda unavoidable.

The 800lbs has a different design that seems to work against it. Perhaps i have a faulty part but it looks the same as the others and will not hold 800lbs.
