User manual ELECTRO-VOICE MB100 DATASHEET

[. . . ] Electro-Voice sanctions suspending the System 200TM speakers only when all current national, federal, state and local regulations are taken into account. When the System 200 TM speaker is suspended, Electro-Voice strongly recommends that the system be inspected at least once a year. [. . . ] From the speaker, remove the plastic hole plugs, gently prying them with a small screw driver. 2. Screw the eye bolt into the insert until the shoulder has contacted the plastic. Finger tighten eye bolt until correct alignment position is obtained, a maximum of one-half turn (see Figure 2). CAUTION: OVER TIGHTENING THE EYE BOLT WITH A WRENCH, SCREW DRIVER, etc. CAN RESULT IN SYSTEM FAILURE AND INJURY. Use certified hardware rated for overhead lifting to suspend the speaker (see Figure 3). STRENGTH RATING The Mb100 Eye-Bolt Attachment Kit and the SystemTM 200 speaker enclosure are rated for suspending only one speaker (5:1 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 M8 eye bolts. The eye bolts are not rated for angles greater than 45 degrees (see Figure 2). An exception to this would be the eye bolt which is used for speaker aiming and not for a main load-bearing point; the angle on that eye bolt can exceed 45 degrees.
