A foot for slack from the pmt to mounting on the wall, 13' to the top of the wall and then another foot to get to the cable tray, then XX feet to the rack
Two cable trays already exist but there is a 2-3' gap that needs to be filled. It is proposed that the current cable tray (located a couple of feet above the Veto Wall) be removed and places a foot above the Veto Wall, for right side cables that need to run to the other side of the wall.
