This power outlet can be installed on nearly any case but is commonly installed on pedalboards. It can also be very useful in guitar vaults, merch cases, computer/recording cases, etc. It is designed to send power to the outside of the case from an internal power source - usually there is a power inlet installed with one of these. It mounts flush and has a female plug on the outside of the case with a male plug on the inside of the case. It has a 115 volt rating at 20 amps. We can also install 30 amp twist-lock or regular style, 220 volt IEC inlets/outlets, etc. Let us know if you have questions!
