ABSTRACT:
A storage cabinet for printed circuit boards is provided with a housing having a pair of substantially parallel and opposed flat surfaced support members on each of which is secured a plurality of printed circuit board retaining plates arranged in edge to edge relationship. The retaining plates are removably secured and held to the support members by inter-engagement means comprising a plurality of locking bars and at least one locking ridge integrally formed and projecting from the rear surface of each of the retaining plate. The locking bars have in cross section a portion overlying the plate and form therewith a lateral channel. The abutting surface of the support member is provided with a plurality of flexible first and second fingers integrally formed with the supporting member and projecting out of the plane of the supporting member. The first fingers are bent downwardly in a lateral direction opposite the second fingers to engage the locking ridge. The second fingers are bent downwardly and laterally from the plane of the support member to enter into the channel formed by the locking bars, whereby the first fingers act to continually urge the first fingers into the channel.
