i asked Jerry about the working load considerations for the M15 and M17 standing rigs. he wrote - "1/8" 1X19 wire has a breaking strength of about 2800 lbs for 316, about 2100 for the cheep stuff. The RTB should be at least this strong, and a good one with 1//4" stainless ends probably is. "The Garhauer adjusters that I used on the M-15 are probably not that strong (altho they might be), but the 1/8" wire has a HUGE safety factor. I doubt that the loads on a 15 are ever as much as 1000 lbs. That's a safety factor of almost 300%. MacGregor uses 1/8 wire on his 26, and I doubt if it's 316. "I believe you're talking about Hyfield levers? I'd guess that 500 is plenty for a 15 with it's 3/4 rig; iffy on a 17, either Sage or Montgomery." -- :: Dave Scobie :: former M15 owner - www.freewebs.com/m15-named-scred :: M17 #375 SWEET PEA - www.m17-375.webs.com On Thu, Sep 4, 2014 at 8:59 AM, Mike Graf <grafsriverhouse@me.com> wrote:

Similar to quick release shackle used on Com-Pac Mastender System.
Attach loose forestay, swing down shackle to tighten, insert pin to secure! Easy peasy!
I've ordered three for shrouds as well. Easy rigging tuning.
