Bard 141-486BX is an OEM intake damper blade support supplied boxed, used in Bard wall mounted HVAC equipment to support and stabilize the intake damper blade so it stays aligned and moves smoothly during ventilation or economizer operation. If the support is bent, worn, or damaged, the damper can bind or sit crooked, which can reduce outside air control and create air leaks. Replacing this Bard factory part helps restore proper damper blade tracking and dependable intake damper operation, and it is best practice to verify fit by matching your unit model and serial to the correct Bard parts breakdown before ordering.
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.
