This adapter kit bridges the coil and the air handler or furnace cabinet, ensuring a secure, properly aligned connection that maintains airflow integrity through the system. Licensed HVAC technicians use this component during coil installations or replacements where the coil and furnace cabinet widths require an adapter to create a flush, sealed fit.\u003c\/p\u003e\u003cp\u003eThis adapter kit is suited for residential split-system cooling or heat pump applications where a B-width uncased evaporator coil is paired with a gas furnace or air handler. It is commonly installed in upflow or downflow configurations depending on the system layout. Use this kit when the coil and furnace or ductwork opening require alignment adjustment to maintain proper duct sealing and system airflow performance.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDesigned for B-width uncased evaporator coils\u003c\/li\u003e\n\u003cli\u003eAdapts coil to furnace cabinet or ductwork opening for proper fit\u003c\/li\u003e\n\u003cli\u003eSupports secure, sealed coil-to-furnace connections in split-system installations\u003c\/li\u003e\n\u003cli\u003eOEM part from RUUD ensuring fitment consistency with compatible systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style adapter kit for use with B-width uncased evaporator coils installed on residential HVAC furnace or ductwork systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician.
