You might see something like this on the Powerlet site. Like so many of our connectors, cables and adapters, they did copy our designs. If you ever get a hold of an old Gerbing catalog, you will see all the cables and adapters we were making for them and Harley years before Powerlet was in business. Available in 3' or 5' length, choose above.
