Abstract: A printed circuit board retaining device for use in securing a printed circuit board in an elongated slot of a rack provides an efficient design allowing for the utilization of an off-the-shelf screw in the device. A screw having a head located within a first end piece interconnects the first end piece, at least one elongated wedge, and a second end piece. A clutch assembly, also retained within the first end piece, is coupled to the screw by a tool configured to engage the screw head. The clutch assembly has a first and second clutch head. The second clutch head being attached to the opposite side of the tool configured to engage the screw head.

Abstract: A guide device is disclosed which assists in the positioning of cards in a card cage by adding to the front of a channel retaining a card edge a V-shaped entrance formed by complimentarily shaped guide members. The guide members each include a peg which is inserted through an associated hole in front of the channel into an associated aperture in a base member. The peg and associated base member aperture are complimentarily sized to permit the peg to be retained by the base member. The guide members are attached to the base member via flexible ribbons.
