Abstract: A container for the storage or transportation of printed-circuit boards comprises an open-topped box with rectangular support plates inserted in vertical grooves of opposite walls. Each plate has several oblique slots, parallel to one of its diagonals, accommodating sliders by which circuit boards of widely varying sizes can be retained thereon. The sliders can be immobilized on the plate by quick-release clamps and are orientable in mutually perpendicular positions for gripping a horizontal or a vertical edge of a circuit board to be supported on four sides.
