ikea built-ins Ikea Akurum cabinets 36" wide x 24" high with white high gloss Abstrakt doors. We placed them 8" off the floor. The IKEA rail system needed at least 3 stud screws with 3 toggle bolts in addition. Total dimensions are 12' x 24"H x 13"D. We also had end caps but decided not to install them because the ends were close enough to the walls.
