Abstract: A circuit board storage cart assembly for transfer of circuit boards between assembly or work stations. The cart has end frame members and cross frame members. The end frame members have swivel casters for mobility. A pair of opposed channel assemblies each having a plurality of corresponding left and right-hand L-shaped channels are paired so that each pair of channels may support a circuit board. The plurality of channels of each channel assembly are vertically connected by two outer posts adjacent and interconnecting the outward ends of the channels and a middle post interconnecting the inner ends of each channel. Each channel has two sloping portions with each portion sloping downwardly at a five degree slope from the outer ends to an apex at the inner ends to define a "V" angle in order to prevent the delicate boards from inadvertently sliding out. The outer posts have stops adjacent their ends and the ends of the outer posts are disposed in a tubular member.
