This rolling case will fit multiple fixtures, equipment, cabling.
It was designed or the ADJ ACCU ROLLER and ACCU SCAN. Both were 22.5" X 11.5" X 9". Therefore those minimally are the inside dimensions X 2 because it fits two.
It would be about 23" X 23" X 10" give or take with wheels and a nice transport handle(NOT MEANT FOR LIFTING).
