The Bard 137-722BX Coil Riser (Boxed) is an OEM mechanical support component used in select Bard packaged wall mount and I-TEC style units to help position and stabilize the refrigerant coil assembly so tubing and coil alignment stay correct inside the cabinet. When a coil has been replaced, shifted, or damaged during service, installing the correct riser helps prevent rub-through, vibration wear, and fitment issues that can lead to leaks or airflow restrictions. Because fit varies by model and production series, confirm compatibility using your unit model and serial number or the applicable Bard parts breakdown before ordering Bard 137-722BX.
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
