Technical Kwick lift car ramp

Thinking about building a Kwick lift, someone who has one and can take a little measure for me?
Width thickness and so. Even on the lift pipe, diameter and width

 

if you leave your ride parked on one be sure to have a good seal in rear of trans

 

Had one and hated it . Sold it to a kid with an import so he could change oil.

 

What made you hate it?

 

How do you get a car on it when it don't run ? Too hard to get under to work on the car.
Jack stands are better and take up less room. When not in use it is a pain to store.
Some people like them , did not work out for me. Fortunately I did not buy mine took it in for some labor owed me for a car I worked on. Sold it for half the bill owed and was lucky to get that . Had it on the internet for 4 months before it sold.

 

good to know - thanks!
