JBL Control 29AV-1 Manual - Eyebolt Applications

Eyebolt Applications 

For Installation of

Control 29AV & Control 30 

When suspending JBL Control 29AV or Control 30 loudspeakers, you MUST utilize 

Load-Rated

Steel Forged Shoulder Eyebolts.   The load rating must be stamped on the side of the eyebolt 

and there must be a shoulder, as shown in Fig 1.  The correct threading for the Control 29AV and 

Control 30 is M6. This means that the threaded shaft has a diameter of 6mm. The threaded shaft 

length will vary according to which insert point is being utilized. 

Top & Bottom Inserts -- When using the installation points at the top and bottom of the 

cabinet, where the flat surfaces are, the eyebolt threads directly into the insert. Be sure to tighten 

the bolt all the way down so that the shoulder is snug against the surface of the cabinet. To do 

this, you must ensure the correct length of bolt so that the threads do not “bottom out” (stop 

turning) before the shoulder reaches the cabinet surface. For the top or bottom inserts, the shaft 

should be 12mm (1/2 inch). See Figure 2: 

For top or bottom inserts, use 6 

mm x 1mm pitch  x 12 mm thread
