There is one quality I like about this holder that I don't have. There's a hole in the side. I mount the jack on a swiveling tire holder. The original intention was to thread the bolt through the jack post and secure it with a wing nut. Purchasing this holder allows me to leave room between the tire holder and get rid of the small spring brace that the jack came with. I use two of these to set up the jack. The third holder is on my other jack.
