I put this here since it involves ducting. I have one of those over the stove combo microwave vent hoods that vents to the outside which I had to remove for a repair. My problem now is hooking the duct back up because I’m in such a tight space. This is 3.25 by 10 rectangular duct. By the time I get the microwave back into position I ony have about 14″ to work with where it joins the duct coming down out of the wall. I recall when I had my furnace replaced several years ago that the HVAC guys hooked up new to old with a type of flexible rubber boot that allowed them to make that junction with ease. Try as I may I can’t find anything like that. Trying to interpose a short piece of rigid duct between the MW vent outlet and the existing duct is next to impossible. Help please! This has been on my honeydo list for a couple of weeks and time is running out.

Good luck! This is the type of job that separates the REAL DIYers from the wannabes.
No doubt. Now to my question about an accordion type rectilinear duct that can be attached to one side and pulled up to the mating side of the existing duct.
Don't forget that it needs to be grease resistant and have a modicum of fire resistance.

I assume this is a straight up application.
You can hook up the exhaust with rigid. Using the two pc rectangular duct (what's available here at a box store, lumberyard), cut a bit bigger (1'') than the area to fill. Slip one pc up into the existing pipe, then the other pc, snapping it together as you go. Bring the now joined pc back down (or up) into the other existing duct. Tape together both ends with the aluminum tape also found in the same dept as the duct.
Or call an HVAC installer and ask them to make you up one of the flex's you are asking about.A great place for Information, Comraderie, and a sucker punch.

Hey, maybe just use an old accordian? A dead accordian is a good accordian.

Believe it or not I actually have an old accordion. That would be one for a future owner. ;)
any sheet metal shop should be able to make up a "slip" connector for you . Bring in your dimensions and they can fab up two pieces, one slips inside the other .
Thanks to all. The custom sized slips into another seems to be the best way to go. I guess this means taking the MW down, slipping a custom piece inside the existing duct, adding some sort to colar to the MW vent outlet, remounting the the MW and then sliding the custom piece back down inside the colar and then finishing with tape or mastic. Thanks for the ideas.
If your duct in at the wall is round then you can transition to round at the MW and have a round (actually cone shape) transition made as well. the rectangle to round transition is an off the shelf part . Again good sheet metal shop.
Get the collar ready, leave the micro up there, you should be able to tape off around the existing flipper, you won't be able to raise it up with the collar attached beforehand. Take a straight pc that you've sized to fit with the collar in position. But b/4 you collarize it, stick the straight up onto the other duct. Place the collar and then bring the other one down to it. No? That metal tape will hold quite a bit, you wont need much overlap.
Best of luck.A great place for Information, Comraderie, and a sucker punch.
