I built an 800 lb 4x8 foot workbench and installed these wheels to easily convert my garage from park and workshop mode. I expected the wheels to do the job but didn't expect how easy it would be. These wheels can move the workbench like a shopping cart. I used to try to avoid working in the shop unless I had a long day to focus on a project. It took too long to set everything up. These wheels completely changed my flow. Now I will work in the store even if I only have 30 minutes because the setup is very easy.
