The Buckingham, the Port-A-Wrap XL has a versatile rope retention, lifting and 3-1/2" diameter barrel anchoring system. Tensile strength of 60,000 lbs. and an average working load of 6,000 lbs. Accepts 7/8" and 1" rope.
Made of nickel plated steel unlike most of the other porta-wraps on the market. Those are made of stainless steel that does not dissipate heat like plated steel. As a result, your rigging ropes will wear out much faster due to heat build-up. So spend a little more now, but save in the long run by not having to replace your rigging ropes as often.
