It's tremendous, but not that tremendous. I hang my hammocks fairly loosly with the ridgeline sometimes luffing just enough to keep the netting off me. Maybe 250#'s on the ropes? However, one thing I'm about to do is change my suspension lines to Amsteel Blue to maybe shave few ounces off the pack weight. That stuff replaces wire rope on 4WD winches, pound per pound.

So, 4500 lbs. capacity for a .8 oz. aluminum beener, or a 3/8ths" threaded steel shackle at 2200lbs. and about 1 lb. weight. Oh, yeah, that makes sense!
