Generator Guru says:
These connectors are used on Generators, ATV, Motorcycles and other small engine equipment. They connect a series of wires together, making it easy to remove at the press of a lever. On your generator you will find various sizes of these connector blocks.
Also good for replacing connector blocks you cannot match.
