Some tin from today.

Is that the t-stat wire going through the return grille?

Only two things I would have done differently.

1. Standing S-Slips for anything 18"+ in width (SMACNA standard).

2. The square throat/radius heel elbow coming through the wall is less than ideal, especially on the supply side. That is the 2nd worst elbow flow wise (after square throat square heel without vanes). A square elbow with vanes in it would have been much better IMO seeing as how a 1x radius throat would have pushed the duct too far off the wall.

Otherwise it looks pretty good to me.

Stat wire, yep. Not our work. We did nothing with the return.

Lash i know a S-Clip but what is a standing S-Slip ?

Thank you,
That would be for added stiffness correct ?
Like a garage door has to support the panels in the up position.

You got it.

Thanks Lash,
I try to learn something new once a day.

ridged s lock is what I know it as...

Guy that makes our metal, I swear his 26ga is closer to 24ga and his 24 is closer to 20ga metal. The shop that made the metal also made the s'lock(as we call it) Trust me it is plenty stiff. The last ridged S we got sucks compared to the old sealtite stuff we used to get.

Did You have to wax the duct or was that included in the pricing? Whenever I got carried away with two sheetmetal screws in each hanger I was assured an orcestra of oil canning music. But it is a job worthy of metal art! ds.

Very nice. I love seeing a good Duct job. I myself have been mostly self taught, and take great pride in what I do. I love to see the inside curves on the elbows, and admit I still need to learn how to do that.

Metal shop does it on the computer. Spits the metal out, add cross brakes,pittsburghs, snap lock, drive hooks, whatever it needs. Use a slip roll to form the radius pieces. Assemble and done. They can make about anything.

Got an overhead spiral duct job this week. Never used the stuff before.

[g_friendly]

inside radius that is cool! I fight with our sheet metal shop to have them install them. They always complain that it is to hard.

[jimmyed]

Computer cuts it out, roll the piece in a slip roll, run it through the pittsburgh machine and assemble.

Not that hard at all. I think these broadways had a 3" throat. Metal shop can make it however we want.
