Order Custom Duct Fittings Online — Any Size, Made to Order
Yes. Pick the fitting type, enter your exact inlet/outlet dimensions, gauge and material, and you get an instant price on the screen — no phone call, no quote wait. The part is then fabricated to those exact dimensions and shipped to your job site; orders ship in 1 business day. There are no minimum-order quantities, so a single odd transition is as easy to order as forty identical elbows.
Why order fittings online instead of the supply house
The local supply house stocks a fixed set of standard sizes. The moment your job needs a 14×8 to 10×6 transition with a 12-inch throat, or a 22.5° elbow, or an offset that clears a specific beam, you are either waiting on a special-order that takes a week or you are back at the brake making it yourself.
Ordering online removes both problems. You specify the exact geometry, the software prices it instantly from the real flat-pattern sheet usage and labor, and the part is cut on a CNC plasma table and formed on an automated brake — the same tolerances every time.
For contractors this turns a half-day of field fabrication into a two-minute order placed from the truck.
What you can configure
Every common sheet-metal fitting is buildable to custom dimensions:
- Straight duct — any width, depth and length up to a full sheet
- Elbows — any inlet/outlet size and throat radius, square or rectangular
- Transitions & reducers — any inlet-to-outlet size change and taper length
- Square-to-round — rectangular inlet to any round outlet diameter
- Tees, wyes, offsets, return boots, plenums, end caps — built to your measured dimensions
Material and gauge are yours to pick too: galvanized steel, aluminum, or stainless, in 26 through 20 gauge.
How instant pricing works
The price you see is not a placeholder that gets corrected later. It is calculated from the actual flat-pattern square-inches your dimensions require — how much sheet the part consumes — plus the estimated fabrication labor. Change a dimension and the price updates on the screen, so you can trade a half-inch here or a gauge there against cost before you buy.
Because it is a real order the moment you check out, every line carries a dimension drawing and a 3D render so you can confirm you specified the part you actually meant.
Lead time and shipping
Made-to-order fittings are fabricated after you order — there is no shelf inventory — so plan on 1 business day for fabrication plus transit. Larger orders ship LTL freight quoted at checkout. For a single emergency fitting due tomorrow, field fabrication is still faster; for anything you can plan even a few days ahead, ordering is cheaper once you count the brake hours it saves.
