What do you do when you need to occasionally haul cabinets in a trailer that's set up to carry tools? Brian Campbell knows.

He figured it out when he was fitting out the interior of his cargo trailer. Instead of permanently screwing shelves onto the wall, he made them removable by using a pair of interlocking cleats. The first cleat is fastened over vertical spacers on the wall. The second cleat is on the bottom back edge of the shelf and laps over the first. Decorative brackets prevent the shelf from sagging.
