And when they do shear, they are a pain to remove.

I remember when I first brought Quick Frame onto FRC 1939 (Hey Gavin), I had a lot of resistance from the mechanical group. They did not trust the plastic connectors. I had to twist arms to just get it used on some minor support pieces. When you introduce it to the team, gather your evidence about strength and best applications. This http://www.chiefdelphi.com/forums/ar...p/t-79559.html discusses the product as well as another supplier EZTube.

449 has used quick-frame extensively every year that I've been associated with the team. It's a very nice material.

That said, the connectors do not have the strength of proper gusset plates, so you must reinforce them in high-load situations.

Also note that given the nature of the connectors, they're less tolerant to errors in framing member length than a match-drilled gusset plate construction - it's rather hard/annoying to push the connector "not quite all the way in" in a way which allows you to keep things square if the lengths of your framing members are slightly off.
