For my originals band we have a touring rack that we use. We run, axe fx and kemper directly too 2 power amps in the rack. From there they go too 2 Guitar cabs on stage. I wanted a quick way of being able to access the sockets on the back of the power amps. So I wired them up too these sockets. They are extremely high quality, a very hard wearing durable plastic and work flawlessly every time! Highly recommend!
