Impact Acoustics(?) Wiring System Brackets are an efficient and effective distribution solution for your home or small office audio/video/telephony/control system. Ideal for small systems in homes and apar?ents, the smaller size also makes these brackets ideal for ?sub-system? breakpoints within your home theater or distribution system. Brackets are available in 11in and 14-1/2in heights, are single module width, and include a wrap-around cover. These brackets accept Impact Acoustics(?) structured wiring modules and have been designed to accommodate other common modules as well.
