The Right Fit for YORK® Equipment

YORK® R-Series Prefabricated Curbs simplify installation of ventilation equipment and prevent issues common to site-built curbs with integrated flashing and continuously welded seams.

Thick insulation ensures sound attenuation. A vast array of configurations and heights are available to match roof designs and provide secure connections to ductwork and mounting of fan or ventilator. Our prefabricated curbs are more cost-effective than field-built wooden or concrete curbs.
