This wooden replacement roll brush assembly fits Rainbow/Rexair power heads for D4C SE Performance Edition (center belt only), E2 power nozzle (PN2, PN-2, PN3), E3, one-speed E series E1/E2, and two-speed E series type 12. The belt engages at the center of the brushroll - this distinguishes it from the end-belt R-1866 variant (CWP RX201).

Features nylon bristles, ball bearings, and black plastic end caps with thread protection. Compatible replacement for Rainbow/Rexair OEM parts R-5590, R5590, R5590C, and R-5590C.
