A support rack for a substantially planar circuit board includes first and second spaced apart sides. The sides define a plurality of spaced apart product receiving support surfaces where corresponding surfaces on each side are parallel to one another and spaced apart by a central region to form a U-shaped rack. Between pairs of support surfaces on a selected side are truncated, trapezoidal-like protrusions which terminate in product retaining clips. Integrally formed braces can be provided to increase rack strength.
