5346 forms the southern wall of room 3 and the northern wall of room 4. It is equal to SU 5345, the north-south wall that serves as the southern part of the western wall of room 3 and the northern part of the western wall of room 4. It is covered by SU 5383, the floor preparation in room 3, and SU 5317, the floor preparation in room 4. The wall seems to be an earlier part of the same construction phase as the floor preparations. The eastern end is cut by a robbery (SU 5409), which seems to have been related to the removal of a third ashlar block of the eastern end of the wall.
