This 8-foot F-shaped extrusion mounts on the interior wall of your trailer and allows for a 1/4" thick sheet of plywood to be mounted perpendicular to it to form a bulkhead wall or other interior partition wall.  It has a satin anodized finish for beauty and long life and can be bowed to fit the interior curved side walls of an Airstream or other aircraft style trailer.
