I made my own rack mounts for my power strips sometime ago but I thought I would post it on my blog as it saved me a few notes. I made them with some scrap plywood that cost me nothing and some right angled brackets. The right angled brackets had to be modified simply by putting a second bend into them so they could screw into the plywood. As it happens the holes in the brackets were to be the correct size for me to simply bolt them to the rails in the rack without further modifications. 😀 All I had to do then was use some self taping screws and screw them into the plywood so the extension lead could lock onto the plywood.
Below I have pictures of the rack mount brackets and the before and after shots of the rack 😀
