Single stud fittings can be attached to these anchor plates and used as suspension points. Each of these anchor plates also has a M8 thread to accept rated forged M8 shoulder eyebolts. In addition to these points there are three additional M8 threaded points; two on the handle side, and one on the rear. These points can be used for suspending Zx3s vertically, horizontally, individually, in clusters, or to attach to EV mounting brackets. Working load limits for the Zx3 and fittings are shown in Figure 2. Prior to each use, inspect the grid assembly or suspension point(s) and associated hardware for any cracks, deformations, broken welds, corrosion, missing or damaged components which could reduce the grid assembly or suspension point(s) strength. Never exceed the limitations or maximum recommended load intended for grid assembly design or suspension point(s). As an added safety measure, it is suggested that the user install a second suspension point back to the grid (or building structural supports). [. . . ] Spray adhesive such as 3M Super 77 may help adhere the backing material to the grille. Additional Precautions to be Taken Prior to painting, be sure to take precautions not to get paint into the transducers. This can be done by masking the grille, temporarily removing the grille and masking the transducers, or by temporarily removing the grille and temporarily removing the transducers. [. . . ]
