SPACE SAVING MIC/WALL 16 way BOX. This "Toblerone" Wall Box takes up far less space than other products. Leads protrude only half the distance and are much easier to identify without bending down. The lid is silk screened with channel identification numbers on both sides. Should two boxes be used to double the capacity, the second box`s channel numbering will be numerically correct by simply turning over the second box`s lid which is suitably numbered on the underside 17-32. The box is made of steel 1.6mm thick and is drilled for 16 industry standard D type cut out connectors. Socket securing holes are tapped M3 with suitable screws provided. The rear panel has both keyhole and conventional mounting holes plus a 25mm dia. cable access hole. Both ends have 25mm knock outs which are aligned so that cables can pass from one to the next when mounted in a line. Black stove enamelled finish. Both sizes only protrude from the wall by 50mm and are just 50mm high, length 550mm.
