Rapco manufactures FAA PMA approved propeller de-ice brushes for replacement in BFG and McCauley brush assemblies. Our specially formulated carbon compound offers increased service life by reducing wear at altitude. In addition Rapco products offer a substantial savings over OEM pricing. The brush and holder assembly replacements for McCauley block assemblies come with brushes, springs, leads and terminals all attached to an aluminum mounting bracket. There are either two or three carbon brushes per cluster depending on the part number. When ordering, it is important to remember that there is one block assembly per engine, and two brush and holder assemblies are required for each block assembly. If the brush and holder assembly has a part number ending in -1 or -2, one of each dash number should be ordered per block assembly.

Part Number Conversion:

• McCauley de-ice part numbers convert to RAPCO by simply adding an RA to the beginning.
• Example: McCauley PN. B40012 convert to Rapco PN. RAB40012
