I’ve installed some Simpson DuraTech and was not so impressed with the looseness of fit at the twist-lock joints. Also, the manufacturer shipped in plain cardboard boxes with no padding. First piece arrived badly dented. Maybe Excel puts alittle more into their shipping containers and their pipe fits together tighter?
Good luck.
I used the “supervent” chimney materials which I think is made by the same company and sold by the big boxes. I agree with your comments, the looseness of fit and flakey twist lock joints that don’t “lock” seem kind of questionable, but they are safe once you properly secure every joint with a “locking band” (sold separately of course). Their shipping is horrible, I think every single piece was dented as Arthur described. I had to return some of them and pop dents out of the others. I don’t know how this compares to other brands though…
One thing to watch out for - the locking bands used to be really wide (another dumb mistake on their part) but now they are nice and narrow for a tighter fit. Make sure you only end up with the narrow ones.
