If you're tired of trying to find a screwdriver every time you want to hook up to spring terminals or Phoenix type connectors found on many speakers and amplifiers, these Lil'Piggies are just for you. Once you insert or screw down the tail of the Lil'Piggies into your spring terminal or Phoenix type connector you'll be free to connect and disconnect wires without any tools. And because they are 5 way binding posts, you can insert banana plugs or spade connectors where you couldn't before. Great also for adapting higher gauge wires into connectors that might not be wide enough. The Lil Piggies' 18 AWG solid tails can also be soldered to a PC board or other project to give you instant banana plug, spade lug or bare wire access. Anywhere you need a quick disconnect for a banana plug, spade lug or bare wire you can use Lil' Piggies!
