Ordering Curb Adapters Online? Here’s What You Need to Know
When rooftop units need replacing, a curb adapter is often the fastest, most cost-effective solution. But ordering one can be frustrating—especially if you’re dealing with outdated units, missing measurements, or short timelines.
That’s exactly why we partnered with Kurbhub to built the Madon Curb Adapter Portal—to simplify the process and help you get exactly what you need, fast.
Here’s what you should know before placing your next order.
What Is a Curb Adapter?
A curb adapter is a custom-fabricated piece of sheet metal that lets you install a new rooftop unit (RTU) on an existing roof curb. Rather than tearing out the old curb (which takes time, coordination, and roof work), the curb adapter acts as a bridge between the old and the new, saving labor and minimizing disruption.
Curb adapters are a common solution when:
-
A replacement unit is a different size or brand than the original
-
You’re retrofitting HVAC equipment on a commercial or industrial roof
-
You want to save time and money on installation without modifying roofing
What You Need to Order One
To order a curb adapter, you’ll need:
-
The model number of the existing unit
-
The model number of the replacement unit
-
A few basic field measurements (just in case)
You can learn how to take those measurements in our Curb Adapter Measuring Guide, or use our portal to search by unit and access drawings instantly.
