Name that duct work
I will soon be hooking up four new flexible duct lines, already roughed in. I'll be connecting them to hard ducting.
I have two take-offs with adjustable dampers that are preformed at the flange to fit hard duct. I need to know what the things are called before I can hunt for the ones I need.
Here's a pic. It'll type a thousand words.

It probably is an 8". The system starts at 12" and tapers down. I think these are left over from the last addition job which fed from the very end of the main trunk. I'll be needing 12" and maybe the 8's that I have left. Now I know what to search/ask for.
Thanks for the language lessons.

You don't want to use a hole saw. You'll shred the duct and your hand.
You'll need to use tin snips. You drill a starter hole and then use the snips to cut the circle.
Here's a helpful video...... you tube /watch?v=8QsiOppAU1s

And you will probably want the offset snips with the red handle for straight and left hand turns... they work best for circles. The offset helps keep your hand out of the way of the sharp edges.

He's cutting square duct but I could get some cool snip like that and do the same on my round duct. All the holes will be in place that are easy to work on.
One of the bubbas that installed the system mentioned hole saws he had that I could borrow. I don't want him or his buddies near the system anymore after the stuff I found while roughing in my new ducting. I'm not an HVAC guy and redid their connections better than they installed them.

A hole saw has jagged teeth that will get caught on the ductwork and literally tear it up.
It's a little more difficult cutting a round hole in a round duct but the idea is the same.
Just wear gloves.... fresh cut sheet metal is identical to a razor blade..... trust me.

easy peasy mac and cheesy! a 1inch unibit works well for a starter hole. Just make sure you get the one that steps from 0-1inch (can start its own hole). a good pair of offset snips like Wise will be well worth the investment. I have made a few dollars here and there by using them.

I just put a little money into a set of three snips, red, green, and yellow. They could come in handy doing siding and such too.
Good idea about the unibit. I've been meaning to get one for a while now anyway.
PJmax. I have scars enough to keep gloves on for lots of jobs. You are wise from the years of abuse.

Hope you caught the advice about getting the "offset" ones... they are different than the standard snips.

Don't be a dick. Some are offset more than others and are really nice to use.
I was thinking of something like these, which are offset a lot more than the standard set of 3 that is sold.

Red & green handles don't automatically mean they are offset.
