Brand new Harrington beam clamp. It is rated at 2000lbs capacity.  Very heavy duty and well made, allows you to make an overhead lifting point at any place on an appropriately sized I-beam, from 3" wide to 7.5" wide with a .83 or thinner thickness. These are very expensive at the dealer but you can buy mine at a bargain and have it shipped to your door for free. Please study the pictures carefully and ask any questions you may have. Thanks for looking and please check out the other items I have for sale.
