Abstract: A tote box includes two opposing side walls, and first grooves in one of the side walls and second grooves in the other side wall. The invention includes first and second locator members, each of which includes a planar body section having opposing faces, one of which is adapted to abut the interior side of the corresponding side walls. Each locator member also includes a pair of vertically extending tongues projecting from the one face of the body section and releasably positionable in any next adjacent pair of the first grooves and a plurality of vertically and inwardly extending substantially equally spaced apart tongues projecting from the other face of the body section. The latter tongues define a plurality of horizontally substantially equally spaced apart inwardly opening vertically extending grooves which are more clearly spaced apart than the first and second grooves.A circuit board divider has grooves on both sides of it which face each of the end walls.
