I will 2nd Ed. Check the LISTINGS carefully. And not just the product brochure.
Also, as a reminder, when using all thread rod, the intent is for it to be "vertical". Make sure the product selected accounts for slope if present. R/ Matt Matthew J. Willis, C.E.T.

DO NOT click links or open attachments unless you recognize and trust the sender. ________________________________ We’ve had a lot of projects recently where ‘simple saver’ plastic liner (or something similar) is installed to the bottom of the purlins. I still prefer attaching to the vertical part of the purlin, but that can get tricky, messy, and a bit ugly. We’ve used a lot of the sammy-type products (there are other brands on the market) to hang from the bottom horizontal flange of the purlins – in particular the products that ‘mushroom out’ as they’re tightened. Yea, look at the listings carefully – there are limitations on size of pipe that can be hung, and minimum thickness of the purlin you’re attaching to. Also check the PEMB drawings for any limitations they have for hanging. The maximum point loads can be pretty small. We’re dealing with a couple projects now where we’re installing multiple anchors for each hanger (kinda like a trapeze bar) to keep the PEMB people happy. You can get really creative if you’re willing to get the PE stamp on it.

We have a case where there will be a barrier installed, and the bottom flange is the “only” place to hang. If I’m reading the data sheet for Sammy Sidewinders it looks like there are a couple options, 2” & 3” pipe. Thoughts?
