Just another reason why being UL tested doesn't mean crap to me. A product having the label or tag is not a bad thing. It just doesn't garantee the product is truely safe IMO and certainly says nothing about quaility.

wkpoor, being an inspector, I think you underestimate UL. But then there is nothing wrong with evaluating your product and situation and maybe going above and beyond what the testing lab specifies. I for one would have paid extra for a ceiling support box with MORE than the 2 inches clearance to combustibles required by the UL testing and label, but of course that is not available. I went above and beyond all requirements except that one......had no control over that. Well, looking back now, I could have framed the support box with metal studs but I didn't think of that at the time.
My previous stove was set up the same, except I also had a damper on the stove pipe in the 45° section... I think pulling it from the pipe when I did this install improved my draft a bit.
I went in search of some real 45° elbows, none found in a 200km radius. My one 90° elbow, I'd love to redo in 2x45° sections to give it a larger bend radius. I'm still curious what has less draft restriction (and probably less air leakage), the adjustable 90° elbow, two adjustable 45° elbows, or the 90° corrugated fixed elbow.
But now I'm off-topic.

As the OP I say carry on. I too have never seen a fixed 45. Having 2 or more adjustables seems bound to increase the leaks and or run a cooler pipe.

Not sure about northernontario, but I've looked from them to be made like the solid 90's in sweeper form.
Sure enough on that site Heatfab makes one. A smooth 45 sweeper. Thanks begreen!
I suggest we revive an older thread and move the stove elbow discussion over there... https://www.hearth.com/talk/threads/stove-pipe-elbows-–-regular-vs-corrugated.54120/

Your stovepipe should be under constant vacuum, so no concern with leaking smoke into house under normal operation. In case of chimney fire, I suppose there could be a draft reversal, but then you'll have bigger problems than your adjustable elbows. Only down side I can imagine, with respect to the leakage, is a little cool air getting into the flue... almost certainly too little to matter.

A UL tag does not imply quality, efficiency, or performance... but it does guarantee the prescribed level of safety.
I would rather have a stove that is UL listed then one that is not listed.
