This is the latest addition to my collection of organizers which also act as a backboard for my workbench preventing items from falling down the gap between workbench and wall. My circuit breaker box sits three inches above the top of the workbench. The width of the breaker box is two and a half of these printed sections. I made this backboard section with a holder section on the left half so I could make use of the half of the section not under the breaker box.
