ABSTRACT:
A card frame for housing electrical circuitry mounted on cards comprises end plates (10) separated by front and rear cross rails (12, 14) that mount card-guides (16) in which the cards can slide. Each card guide (16) comprises end elements (28a, 28b) engageable with the front and rear cross rails (12, 14) in first and second positions (FIG. 1 and FIG. 2) spaced in both the top-to-bottom and front-to-rear directions of the card frame. Each card guide (16) additionally comprises a shank (30) formed separately from the end members (28a, 28b) and assembled with them. If the shank (30) is of a first length the end elements (28a, 28b) will engage with the cross-rails (12, 14) in the first positions to accommodate a card of a first height, whereas if the shank (30) is of a second, smaller length the end elements will engage with the cross rails in the second positions to accommodate a card of a second, greater height.
