Suncor Quick Attach Fittings

[Matthew Sebring]

I've not personally used or even encountered these fittings before but for some reason have been asked about them recently by two separate customers in two different applications. One was repairing his own bobstay on his Cape Dory while the other was trying to decide whether or not to buy the hamilton marine lifeline kit which includes them (also, coincidentally on a cape dory). Now I am a big fan of the Hi-Mod fittings personally and will continue to use them in the future but I am curious about these. Looking at their video it's just very hard to believe they will hold. Does anyone have any real world experience with them?
