The Leading Designer and Manufacturer of Rooftop Curbs and Curb Adapters
At Curbco, we believe in getting it right the first time—because in this business, even small mistakes have big costs. A slight misalignment or inefficiency in design can lead to airflow resistance, worn-out fan parts, and wasted energy.
That’s why precision matters. And why experience counts.
With decades of proven expertise and a track record of getting the details right, Curbco delivers rooftop curbs and curb adapters that fit perfectly—every time. From measurement to manufacturing, we think ahead so you don’t have to.
Curb Adapters
Curbco curb adapters connect new rooftop HVAC units to existing curbs with a precise fit that saves time and avoids costly rework. Built for durability and airflow efficiency, they make retrofits faster, smoother, and more reliable—every time.
Rooftop Curbs
Curbco rooftop curbs are built to match the exact specs of your HVAC unit, ensuring proper airflow and a secure, precise fit. We source dimensions directly from the manufacturer, so your curb arrives ready to install—saving you time, reducing risk, and helping your system perform at its best.
EasyCurb™ (Knockdown Curbs)
The EasyCurb™ by Curbco is a proprietarily designed knockdown curb that provides dependable structural support for rooftop AC units and other equipment. Designed to match any make or model, EasyCurb™ simplifies transport and assembly without sacrificing strength—making it the go-to solution for flexible, reliable installs.
Roof Equipment Rails
Curbco roof equipment rails deliver the strength and stability your HVAC system depends on. Built with 18-gauge galvanized steel, internal bracing, and continuous welded seams, our rails are engineered to support over 7,000 lbs—ensuring your equipment is as secure as it is efficient.
Metal Building Curbs
Curbco's metal building curb is a precision-built base that secures HVAC equipment to a metal roof, creating a stable, weather-tight connection that supports proper airflow and long-term performance.
Fan Curbs
Curbco fan curbs provide sturdy, reliable roof support for fans and ventilators across a variety of roof types—including flat, pitched, metal, or ridged, with or without insulation.
