All works smoothly. They extend a bit further in work area.

The frames, the hardware and the wheels are much beefier, heavier and stronger. I have a huge quartz work bench that probably weighs 300-400 pounds. Bought these for a router cabinet/bench.

You can eyeball/measure the install location by visually inspecting the mechanics of the foot lever. Predrilling the screw holes is needed.

They tend to drop to the stationary position when i move the saw. When i raise my bench they are not perpendicular to the floor. No measurements or even suggestions on instillation height.

What a bummer. Only for the purpose of saving other people money aggravation and possible injury.

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.
