R-4375, R-2800, and R-1650 Main Housing
Current revision for the model R-4375C and R-2800C power nozzle. Both models use the exact same parts, they just look slightly different.
This item is also an exact replacement for the R-1650C and R-1650A model power nozzle. The color is darker on this item compared to the light brown housing on the R-1650 series.
