I purchased this chain sling so that I could connect 4 horizontal plate lifting clamps to my hoist to move heavy sheet goods from the pallet to the plasma table. I can now safely move 4'x8' sheets of steel weighing over 150lb easily and accurately to a table waist high.I've been using this unit for about 6 months now and it has been working great. No signs of wear or corrosion.When I purchased this unit the chains were too long for my application. All you need to shorten the length of the chain is a punch and a hammer to push out the roll pin. Cut the chain to length and reinstall the hook. Make sure you use new roll pins.
