The GridLinkâ„¢ Rigging Beam System provides the foundation for building quick and reliable loudspeaker suspension grids and speaker bars using predictable load-rated, modular and off-the shelf components. GridLinkâ„¢ Rigging Beams are comprised of standard length beams and beam connectors. The GridLinkâ„¢ connectors act as a heavy-duty beam couplers and load-rated suspension point. In addition, they pivot horizontally to create a wide variety of angles, grid sizes and shapes including rectangles, squares, hexagons and triangles.
