The height of rack rail is determined by the number of rack units required for mounting the equipment. The design of racks and rack rails is specified in ECIA - EIA/ECA-310. Each rack unit (U) is equivalent to 1 + 3 ⁄ 4 in (44 mm). Most rack rail is in sizes from 2 units high (3 + 1 ⁄ 2 in or 89 mm) to 54 units high (78 + 3 ⁄ 4 in or ...

A rack and pinion has roughly the same purpose as a worm gear with a rack replacing the gear, in that both convert torque to linear force. However the rack and pinion generally provides higher linear speed — since a full turn of the pinion displaces the rack by an amount equal to the pinion's pitch circle whereas a full rotation of the worm screw only displaces the rack by one tooth width.
