A seat having a seat leg assembly for use on a mobile platform, especially on an aircraft. The seat comprises a front seat leg, a rear seat leg, and a spreader bar coupled to and extending between the front seat leg and the rear seat leg. The spreader bar has a door. The door is movable between a closed position in which the door prevents access to areas beneath the spreader bar and an open position in which the door permits access to areas beneath the spreader bar. In this manner, the open door allows an installer to grasp electrical cabling beneath the spreader bar and feed the cabling through a hole in the door so that the cable can be connected a connection point on or adjacent to the seat track.
