The GRD18 is a flying and stacking grid designed for Alcons Audio's LR18 line-array modules and LB18 line-array extension modules. This rigid frame structure enables both flown and ground stacked configurations of speaker arrays. Suspension can be achieved through multiple hoist points positioned across the top of the grid or via a central single pick-point bar for smaller installations. All connection points feature 14mm (0.55-inch) attachment locations compatible with 1.5-ton shackles. Weighing 20 kg (44.0 lbs), the GRD18 carries a 10:1 safety certification, supporting up to twenty-four LR18 cabinets or thirty-two LB18 modules. The grid accommodates mixed configurations with equivalent weight loads, providing versatile deployment options for both temporary events and permanent installations where multiple line array modules need secure mounting.
