EBK-1

Eyebolt Attachment Kit

Figure 1  Lifting Eyebolt Installation

General Description:

The EBK-1 attachment kit contains three lifting eyebolts which screw into the inserts provided on the EVI-12
and EVI-15 speakers. The lifting eyebolt attachment points can then be used to suspend the EVI speakers
using hardware rated for overhead lifting.

Hanging Instructions:

The speaker is hung using one or two main lifting chains with a pull-up point in the back for aiming. Two
lifting chains can be used to prevent the speaker from swaying, but both of the rigging hardware (shackles,
etc.) must fit through the 25-mm (1-in.) opening.

Suspending any object is potentially dangerous and should be attempted only by individuals who have
a thorough knowledge of the techniques and regulations of rigging objects overhead. Electro-Voice
sanctions suspending the EVI speakers only when all current national, federal, state and local regulations
are taken into account. When the EVI speaker is suspended, Electro-Voice strongly recommends that
the system be inspected at least once a year. If any sign of weakness is detected, corrective action
should be taken immediately.

Installation Instructions (See Figure 1):

1. Remove the 3/8-16 shoulder bolts from the speaker.

2. Screw the lifting eyebolt into the insert until the shoulder has contacted the wood.

3. Finger tighten eyebolt until correct alignment position is obtained, a maximum of one complete turn (See

Figure 2).

CAUTION: OVERTIGHTENING THE EYEBOLT WITH A WRENCH, SCREWDRIVER, ETC.

CAN RESULT IN SYSTEM FAILURE AND INJURY.

4. Use certified hardware rated for overhead lifting to suspend the speaker (See Figure 3).

Strength Rating:

The EBK-1 Attachment Kit and the EVI speaker enclosure are rated for suspending only one speaker (8:1
safety factor). Hanging any additional weight from the speaker will exceed its strength rating and
create an unsafe condition. Table 2 lists the strength ratings for the 3/8-inch lifting eyebolts with an 8:1
safety factor. The lifting eyebolts are not rated for angles greater than 45 degrees (See Figure 2). An
exception to this would he the lifting eyebolt which is used for speaker aiming and not for a main load-bearing
point; the angle on that eyebolt can exceed 45 degrees.
