So customer had two post racks already in place in a dedicated equipment room.

Walls are all plywood.

One post of the rack is 3 inches from the wall, other post is 3" from the other rack and then matching two post rack.

So matching two post racks. Wall then 3" then rack 3' then rack 3" then wall.

Problem is there is nothing to attach the wires to coming out the back of the equipment.

Other then the side wall, but no support getting to the wall. Most equipment has rack ears and is not on shelves.

Ideas to support wires behind the racks but keep the space to get into to work.

Maybe something on the sides close to the rail.
