I love these feed through connectors - one of those little things that makes the world go round. I'm often changing amp rack configurations and follow through connectors make life so much easier, compares wit soldered and rivetted connectors. in my case i bolt these to front plates so i can also remove and re-configure as needed - bycareful though, getting the right size nuts and bolts takes careful measurement and can be quite fiddly to install. of course there is nothing to stop you riveting as normal if you wish. they are exactly what you would expect from neutrik - solid, steadfast, reliable. I have had some of these installed in amp racks for more than 3 years without them working loose. definitely recommended.
