D3A, D2A, and D2 Power Nozzle Receptacle
Over time the receptacle in your Rainbow D3A, D2A, or D2 unit can wear. If the power nozzle cord keeps falling out easily, replacing this will fix the problem.
The D3C is a two prong system and will not match this item.
You may find R1224 stamped on top of the receptacle and is an exact match to this item.
