[. . . ] The rigging kits allow the user to rig multiple systems together in horizontal and vertical configurations. The horizontal and vertical rigging kits are an open-ended design, meaning that any system in the EVF and EVH families can rig to any other. The vertical and horizontal rigging plates give the user ultimate flexibility for splay angles from 0° to 45° degrees in 5° increments (0° to 20° for EVF to EVF subwoofer). This system was designed to allow the end user to construct a loudspeaker cluster to fit nearly any application. Figure 13 and Table 4 show the possible connections using the three VRK and HRK rigging kits to connect any EVF or EVH loudspeaker.

Additionally, the VRK kits include a set of low-profile stabilizer bars to both simplify alignment of the enclosures during the rigging process and keep the front edges of the systems neatly aligned. Additional hardware is included in the VRK kits to mount these stabilizer bars. The stabilizer bars mount to the insides of the vertical rigging plates for a clean appearance. Stabilizer bars can be seen in Figure 14 and, installed, in Figure 21. The HRK horizontal rigging kits have a tie plate that is welded to the center of the rigging plate. This tie plate is for suspending the top systems in a cluster and for suspending lower systems below (with usersupplied hardware). It has six holes that fit a standard 5/8-inch shackle (user supplied). Tie plates can be seen in Figure 15 and, installed, in Figure 22. Both the VRK and the HRK rigging plates use arrow designators and a series of letters by each of the mounting holes to ensure that the desired angle is achieved. Refer to Tables 5, 6, and 7 for a description of the appropriate arrow direction and letter. All rigging plates except the EVF-to-EVF-subwoofer rigging plates are symmetrical, meaning that the mounting-hole layouts are the same from the left to the right sides of the rigging plate. The EVF-to-EVFsubwoofer rigging plates are asymmetrical, meaning that one side is for subwoofers, labeled "Sub, " and the other side is for EVF's, labeled "EVF. " This rigging plate must be flipped over depending on which side the subwoofer is on. All user-supplied hardware must be overhead load-rated (using applicable safety factors) for the specific cluster. See section 6. 0 for additional details on load limits and safety factors. 5. 2 EV-I Rigging Primer The following sections describe the clustering of EVF and EVH systems using one of the following three approaches: 1. EBK-M10 eyebolt kits supplied with each system (used in conjunction with other user-supplied hardware). Optional VRK vertical rigging kits, in conjunction with the supplied EBK eyebolt kits and user-supplied hardware. [. . . ] Never exceed the limitations or maximum recommended load for the supports. Miscellaneous Mechanical Components: Prior to each use, inspect all mechanical components (chain, wire ropes, slings, shackles, hooks, fittings, ratchet straps, etc. ) for any cracks, deformation, broken welds, slipping crimps, fraying, abrasion, knots, corrosion, chemical damage, loose screws or missing or damaged components that could reduce the maximum strength specified by the component manufacturer. Replace any damaged mechanical components immediately. Never exceed the limitations or maximum recommended load for the mechanical components.
