Bard 507-309BX - Top assembly (aluminum)

Bard part 507-309BX is an OEM top assembly used on Bard wall mounted packaged HVAC units, providing the correct fit and structural coverage at the top of the cabinet to help protect internal components from weather and support proper panel alignment. This aluminum top assembly is built to Bard specifications for dependable service in commercial and institutional applications, and it is the right choice when a damaged, corroded, or leaking top section needs replacement to restore the unit’s cabinet integrity. Because cabinet parts can vary by model series and production revision, confirm 507-309BX against your unit model and serial number or the applicable Bard parts manual before ordering to ensure an exact match.

What does the "BX" suffix mean?

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.
