Abstract: A modular arrangement of a single light source providing light points to multiple panels by light transmitting fiber strands. Each panel has a pattern of drilled holes and is pre-assembled with a fiber strand secured in each hole. The fiber strands of each panel are bundled and encased into cords for ease of handling and installation of the panel. Fittings on the end of each cord attach the cord of each panel to the light source.

Abstract: A load spacer or support constructed of laminated paper and adhesive material to form a generally "W" shape load spacer or support having a full depth slot throughout the length thereof to accept a tie strap and two trapezoidal shaped hollow load cells defining the slot with the load cells being interconnected by a top sheet or panel having depending flanges along each side edge thereof overlapping and secured to the outer surfaces of the load cells which provides a tension force in a horizontal plane to counteract deformation of the cells under compression. The load spacer, support or batten may be employed in various orientations with respect to stacks of flat sheets of material, such as wall board, panelling, particle board, and the like, and replaces conventional employed solid wood pieces, such as a 2".times.4" wood member having a slot milled into one surface thereof to accommodate the tie strap.
