There are 4 red plates to fill the centre of the lift, they are rated for 800lbs each. They were purchased from rotary as an addition accessory and are great to have with the aluminum Ramps real happy with the setup.
Great shop build man! I'm in the process of doing same size garage with same hoist location you have. How do you find walking around the hoist post with the wall spacing and how far from the wall did u mount the car hoist?
