To save money - and to try out the design to see if it'd work well for me - I bought 4 small steel rings from the hardware store at about $1 each. They work fine and I'm thinking about upgrading to descender rings - the steel hardware store rings work fine for tightening the suspension but although the knot doesn't jam it does get a little tight and finicky when I try to loosen it. I'm using 1" webbing straps that serve as tree huggers as well as my suspension. I have a couple of questions:
1) Anyone had these cheap hardware store rings fail? They're welded and although I bought them a while ago if I remember right they were rated to 200# per ring. The descending rings are rated to over 3000#. I haven't had any problems with the steel rings...is it just a matter of time? Perhaps I should upgrade just based on the strength difference....
2) It seems like the steel rings being smaller diameter is what causes the adjustable knot at the rings to tighten to an extent that makes loosening take a bit longer than I'd like. The steel rings are roughly1 1/8" ID and 1 3/8" OD Maybe things don't tighten down as much with a ring that is larger in diameter (both overall and the thickness of the aluminum used)? I just measured and it looks like the thickness of the steel used is 5/32" or .156" and the rings I'm looking at (from www.whoopieslings.com
) are listed as .3" thick. Anyone out there have any experience with comparing the ease of adjustability of these two types of rings?
