This is a light duty (200 lbs. max), instantly adjustable jack stand used to hold exhaust pipes, cut out flex pipes, aid in fuel tank removal, hold oil pans, joists, drywall, pipes, pretty much any place you need to hold something in place securely while final installation is completed. I call it Fred's "third hand". Any auto shop, pipefitters, carpentry. Overhead drywall and joists. Welders. Light weight, less than 10 lbs. Instantly adjusts from 5 to 9 ft., but can be easily modified to your exact need. NO more "come over and hold this for me". This will save you time and trouble, especially if you work alone and there is no help available.Yeah, you could go to the home store and get SOME of these pieces and cut, drill, weld one together....but it will take weeks to get ALL the special tidbits together. One of the top ten tools I own....and you won't find anything else like it anywhere.
