The cabinet is about 6 feet tall so wanted smaller wheels for it. Have purchased several sets and have had no issues with any of them. Having large fastening screws and washers were a plus.

They work great on smooth surfaces and not so much on gravel. They have smooth operation with good bearings and good mounting plates. Great rollers, easy to install, comes with everything you need.

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.
