EBK-1 3/8” Eyebolt Attachment Kit
The Electro-Voice® EBK-1 Eyebolt Attachment Kit contains three shoulder eyebolts, along with three fender wash-
ers for load distribution, which attach to Electro-Voice® speakers that have integrated 3/8” suspension points.
The eyebolt attachment points can be used to suspend the Electro-Voice® speakers using hardware rated for
overhead lifting. The loudspeaker is suspended using two main suspension points with a pull-up point in the back
for aiming. Two suspension points can be used to prevent the speaker from swaying, but the rigging hardware
(shackles, etc.) attaching to the eyebolt must fit through the 25-mm (1-in.) opening.

Installation Instructions:
1. Remove the 3/8-16 shoulder bolts from the speaker (See Figure 2).
2. Screw the lifting eyebolt and fender washer into the insert until the fender washer has contacted the wood (See
Figure 3).
3. Finger tighten eyebolt until correct alignment position is obtained, a maximum of one complete turn.
4. Use certified hardware rated for overhead lifting to suspend the speaker (See Figure 6).
WARNING: Eyebolts must be fully seated and oriented in the plane of pull (Figure 4). Always use the fender washers to distribute
the load on the enclosure (Figure 5). Overtightening the eyebolt with a wrench, screwdriver, etc. can result in system failure and
injury. Consult the loudspeaker user manual for the loudspeaker load ratings and specific requirements.
