A curb adapter provides an efficiently modified interface between an HVAC rooftop unit (RTU) and the rooftop ports or holes that feed the heating and air conditioning to and from the building. The rooftop ports are built-into a raised external assembly called a curb. Many of these rooftop HVAC curbs were originally set into the roof to accommodate old HVAC units that are either no longer in production or no longer the best choice for the building's current needs.
