Cabinet and rail dimensions for a custom cabinet?
I use rails that are .500 tall and .750 deep. A dense hardwood is best and they must be drilled to accept mounting screws to limit cracking. The notch at the top and bottom of each module is .400. The rail should fit inside this notch with .025″ to spare. So, .375 of the rail should go into the notch. This leaves .125 of the rail beyond the module’s edge. So, based on .500 tall rails, the inside cabinet dimension should be 8.750+.125+.125= 9.000. There’s very little room for error and the cabinet maker needs to be right on. It’s pretty difficult to have a cabinet made that works without providing a panel for them to use. Panel dimensions are on the technical page.
