24 in pantry. A and B were done before the switch to the stock 50 in lower doors: A puts a column of roll-out trays behind each tall door, B attaches each door to a pull-out shelf tower so the whole half slides out. C and D are the single-wide versions on the stock door split: C has one column of full-width roll-out trays behind the hinged pair, D fixes both door panels to one 24 in pull-out frame so the whole front comes out (door-mounted pantry frames such as the Kessebohmer Dispensa and Vauth-Sagel TAL Gate are made up to 600 mm / 24 in wide). Waypoint tall cabinets all carry the 50 in lower door, so B as drawn (69 in towers) needs a custom pantry box; the bare UT2424 X 96 shell is sold without shelves for your own hardware, but the rail stays.
