A vertical frame has a lower horizontal bar with opposed ends that pivotably receive the rear portions of two L-shaped members. Forward portions of these L-shaped members have abutments to receive one edge of a roof panel to be supported thereon with another part of the panel resting against the top of the vertical frame. Casters on these L-shaped members allow the rack and its load to be transported. Two of these casters have support posts that are received in slots to limit pivotal motion of the L-shaped members relative to the vertical frame.
