[B-O-B]

I had a rotary 4 post in my shop. I really liked it. positive stops, hydraulic operated cables, never a problem in 17 years of use & was still working great when I moved. I bought it used from a outfit that sold & serviced garage equipment. I installed myself & didn't take long. Make sure your footing is deep enough 4" minimum 6" is better. Ceiling clearance & placement need to be considered also best equipment you will ever invest in. I putt side lights in the top 2' of the walls & it gives lots of light.
