    Original stain relief clip for the model D4C, D3C, and D3A Rainbow. If you are replacing the power cord, then an improved design clip (R2605) is available to work with new version cords.

    This metal relief clip over time could cut into the cord and damage the mounting area of power cord.

    If you are updating the power cord on your D4C Rainbow, the cord has been redesigned for use with the improved R2605 plastic strain relief clip. The new design helps eliminate the issue listed above.

    It is always a good idea to replace these screws that are used for the R747 flange as most times they will be very rusty.

    Depending on the model and time frame that your unit was produced, you might find that your flange only has four screws. All new flanges have eight screw holes so be sure to order eight of these screws when servicing your Rainbow.

    Original version of this screw was longer (image two) and would stick out the other side of the housing. This caused an issue if any rust would form on the end making it difficult to remove. The shorter screw keeps all threads in the motor housing and solved the issue.

    Over time the receptacle in your Rainbow D3C unit can wear. If the power nozzle cord keeps falling out easily, replacing this will fix the problem. Will not fit the model D3A as the sockets are not as wide.

    Item does NOT include spring or pin. Please look under the "Related Items" tab.

    Easily replace your broken latch (clasp, fastener) for all versions of the D4C SE (Special Edition), D4C, D3C, and D3A Rainbow.

    Use a small punch and hammer to remove the brass pin holding in place. The pin has a smooth side and a rough side. The rough side bites into the plastic to hold the pin in place. Punch the pin from the smooth side to remove.

    This item is only available in black because the factory Rexair, LLC no longer makes color matching latches for the D3C or D3A. They also no longer make decal matching latches for the D4C (Special Edition) or the D4C.

    Item numbers R4228, R3833, R2815, R2814, R2622, R1565, R1562, and R1561 are listed on some older latches. This item is the direct factory replacement.
