pended items be inspected at least once a

year and any weakened or damaged parts

be replaced immediately.

The recommended mounting method is the

optional U-Bracket hanging kit, EVI-28MB,

available in black or white.  It attaches to

the 3/8” t-nut locations on each side of the

enclosure, allowing the system to be hung

individually or in an array.  A set of mount-

ing holes for an OmniMount 100 are in-

cluded on each EVI-28MB bracket.

Electro-Voice recommends a minimum

safety factor of 8:1, or greater if local codes

or regulations exceed this amount.  The

EVI-28MB brackets exceed this safety fac-

tor when installed in compliance with

Electro-Voice recommendations.
