Bard part 103-439 is an OEM heat exchanger support offset used in Bard wall-mounted HVAC equipment to hold the heat exchanger in the correct position and maintain proper alignment within the heat section. A support like this helps prevent vibration-related wear, keeps clearances consistent, and supports reliable airflow and heating performance by keeping the heat exchanger assembly properly located in the cabinet. If you are replacing a damaged or bent support during a heat exchanger service, ordering the correct Bard 103-439 ensures the fit matches the original factory layout and reduces the chance of installation issues on reassembly.
* Orders less than $50 may incure a minimum order fee.
