Strain Relief Clip, D4/D3
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.
