ABSTRACT:
A guide frame for the retention of printed-circuit carriers or other slidable articles comprises top and bottom members integrally molded from plastic material, each member including an elongate base with upstanding sidewalls and two sets of cantilevered ribs, the ribs of each set extending inwardly from a respective sidewall at an angle of substantially less than 90.degree. and terminating in a common longitudinally extending bar overhanging the base. The two bars are separated by a distance less than the thickness of a workpiece to be inserted therebetween, the herringbone pattern of the ribs facilitating such insertion from one end but impeding a withdrawal toward that end.
