Both the VRK and HRK rigging kits share the same mounting hole positions and letter designations.  

Tables 5, 6, and 7 apply to both the VRK and HRK kits.  The only difference between the kits is the HRK 

rigging plates have an integral tie plate and the VRK kits use a stabilizing bar.

1. 

Refer to Tables 5, 6, or 7 to determine which lettered hole position to use.  Follow the direc-

tions in these tables for arrow direction and positioning on the cabinet.  Note that “Front” 

will always refer to the front of the enclosure (i.e., the grille).

2. 

HRK kits skip to step 3.  For VRK kits, preassemble them using the supplied hardware by 

attaching the stabilizer bar to both the large and small rigging plates. Attach the stabilizer 

bars to the back side of the plates, using a #2 Phillips screwdriver, the eight M5 pan-head 

machine screws and M5 split-lock washers supplied with the hardware kit. You are now 

ready to attach the VRK kits to the loudspeakers. 

3. 

Referring to Tables 5, 6 or 7 (depending on which systems are being connected), find which 

rigging-plate letter will give you the desired angle. Also pay attention to the arrow direction 

as listed in the table.

4. 

With a 6-mm Allen (hex) wrench, remove the M10 flathead bolts that were installed by the 

factory. Remove only those bolts that are going to be replaced by rigging hardware, in order 

to remain safe and avoid audible enclosure leaks. 

5. 

Using the appropriately lettered rigging-plate holes, attach the VRK or HRK kits to the en-

closure sides using the eight supplied M10 button-head bolts and split-lock washers. Use a 

6-mm Allen (hex) wrench.

6. 

Install any M10 eyebolts that are needed for suspension, pull back, or stabilization at this 

time.

7. 

Ensure that all M10 bolt points in the enclosure have an M10 flathead bolt, an M10 eyebolt 

or an M10 button-head bolt where the rigging plates attach. Do not hang any cluster with 

missing M10 bolts!

8. 

Check all M10 and M5 fasteners and eyebolts to ensure they are tight.

9. 

You are now ready to hoist the cluster and make the final attachments to the building struc-

ture.
