New unit doesn't fit the old curb? We'll fix that fast.
Send us your field measurements and we'll cut, bend and weld custom curb adapters, equipment stands, duct supports and brackets so your crew stays on schedule.

We know what's slowing you down.
The field never matches the plans
The old curb is a different size, the roof pitch is off, or the wall won't hold a standard bracket.
Crews standing around
A crew waiting on a custom stand is the most expensive part of the job.
Your shop can't do heavy steel
Your sheet metal shop is great with duct, but a welded steel stand is a different job.
Off-the-shelf stands don't fit
Catalog stands come close, but on a rooftop close isn't good enough.
Rush jobs during heat waves
When everybody's AC dies at once, you need parts yesterday.
Commercial specs
Seismic brackets and heavy supports need to be done right, with certified welding.
TDS Fab turns a field measurement into a finished, ready-to-install part, often by the next day.
What we build for HVAC contractors
Cut on our CNC plasma table, bent on our CNC press brake, and welded by a certified welder.
Curb adapters
Adapters and transition plates to fit new units on old curbs.
Equipment stands
Condenser, heat pump and mini-split stands and wall brackets.
Duct supports
Hangers, trapeze supports, seismic brackets and base plates.
Frames & platforms
Equipment pads, frames and rooftop platforms.
Panels & guards
Flanges, access panels, hail guards and unit guards.
Heavy gauge parts
Thick steel, stainless or aluminum your brake can't handle.
Standardize your stands. Save on every job.
If you install the same kinds of stands and adapters over and over, we'll build you a standard set with set pricing. Your crews order by name, and your estimators know the cost before they bid.

Great. We cover the heavy steel, the welded stands and the overflow your shop doesn't want to do.

It depends on size and material, and we'll quote any design. Repeat designs kept on file cost less every time.
