An electronic enclosure assembly having a logic chassis, a forward extension member attached to one end of the logic chassis wherein each side of the forward extension member has side pieces, each of the side pieces having a face and a notch. The enclosure further includes a removable chassis having a front side and a rearward side and sized to fit between the side pieces and slidably movable on the extension until it is engaged with the logic chassis. An activation handle having side members is pivotally attached on the sides and at front end of the removable chassis and is movable between an up position and a down position. The ends of the side members and the notches of the side pieces of the logic chassis cooperate for camming the removable chassis into engagement with the logic chassis when the activation handle is moved to its up position and for camming the removable chassis away and disengaging the removable chassis from the logic chassis when said activation handle is returned to its down position. The logic chassis and removable chassis include connectors which are plugged and unplugged together when the chassis are engaged and disengaged, respectively. Alignment means are provided to align the chassis in the vertical and horizontal directions.

A tailgate assembly of a computer including a tailgate member having a plurality of slots behind which may be positioned removable expansion boards, and an EMC gasket between the tailgate member and the expansion boards. An alignment pin projects from the tailgate member on each side of each slot. The alignment pins on each side of each slot guide the expansion board into place as it is being positioned behind one of the slots and prevents the EMC gasket from sliding out of position.

An abrasion control apparatus allowing a drawer member of an electronic enclosure to be inserted into a receptacle wherein the contacting sides of the drawer member and receptacle are made of aluminized steel. The invention includes a double thick side of the receptacle; the side of the receptacle which comes in contact with the side of the drawer member having a window in which is placed a plastic wear strip. The abrasion control apparatus further includes wear strips in a notched portion of the side of the receptacle and a bottom of the receptacle such that contact is prevented between the drawer and the metal sides of the receptacle as the drawer member is inserted into the receptacle.
