Abstract
Abstract A retention device for retaining the forward edge of a PCI or ISA adapter card in a computer frame is provided. The retention device has a channel mounted to the frame opposite a rearward edge of the card. The channel has upper and lower panels which define a slot for receiving the forward edge of the card. A finger is pivotally mounted to one end of the channel and has grooves on a lower surface for engaging grooves on an upper surface of the forward edge. The finger is movable between an engaged position for capturing the forward edge to retain it from moving, and a disengaged position for releasing the forward edge and allowing the card to be removed from the slot.
