Abstract: A tote box includes first and second locator members, each of which includes a planar body section having opposing faces, a pair of vertically extending tongues projecting from the one face of the body section and a plurality of vertically and inwardly extending substantially equally spaced apart tongues projecting from the other face of the body section. When the pair of tongues on each of the first and second locator members are inverted end to end as part of the members and repositioned in the same selected next adjacent pair of the first and second grooves respectively, the spacing of the divider from the end walls is varied.A circuit board divider is releasably positionable in corresponding ones of the inwardly opening grooves in the first and second locator members to extend between them. The divider has grooves on both sides of it which face each of the end walls. The printed circuit board length accommodating distance can be varied by rotating it so that the groove sets face the other end wall.
