A module mounting unit formed from a pair of side plates and a series of U-shaped cross-members mounted between the side plates for slidably retaining a series of printed circuit board modules by sliding the modules in guideways provided in the module mounting unit. The modules each have a resilient tab having a prong with a tapered head. The module mounting unit has a series of front apertures formed to allow the head of each module to engage the aperture at full insertion of the module, thus precluding withdrawal of the module from the rack. The cross-members each have a series of spaced apertures along one leg of the U for engaging the tabs of the modules and a series of alternately-spaced circular and oval apertures to facilitate the mounting of the module guideways to the module mounting unit. |
