I got a few of these recently for my tow truck. (made up a 6 bank panel). The way they interlock, you could make a trimmed out panel in any length you want. The Contura switches are just about the best around. Towards the bottom of the page. You will need 2 of the tools..otherwise the switches will not come out of the panel after you snap them in.
