Modular back wall amplifier racks, built in 3 sizes, 16.5" main mount rails with 4 left and 4 right hand amplifier mount arms,  21" main mount rails with 5 left and 5 right amplifier mount arms and 25.5" main mount rails and 6 left and 6 right hand amplifier mount arms.  The main mount rails have holes for the included 1/4" lag bolts for mounting to your wooden back wall, if mounting to other substrates the holes will also accept 1/4" bolts(not included).  The amplifier mount arms accept up to a 12" wide amplifier.  These kits are setup to run a 3.28" spacing between the amplifier mount surface and the bottom of the arm above.  The main mount rail does have multiple mounting with a 1/2" spacing for adjusting in 1/2" increments, spacing between arms can be decreased to allow more mount arms to mount more amplifiers on a given rail with smaller height amplifiers, additional arms are available without the rails.  CNC laser cut and bent and powdercoated textured carbide black, includes all hardware for assembly and mounting.
