    Two common heights are 3U (a 100 mm card in a 5.25 in (133.35 mm) subrack) and 6U (a 233.35 mm card in a 10.5 in (266.70 mm) high subrack). As two 3U cards are shorter than a 6U card (by 33.35 mm), it is possible to install two 3U cards in one slot of a 6U subrack, with a mid-height structure for proper support.
