An apparatus for facilitating the insertion and extraction of a PC board into and from a card cage, comprising a mounting body, an engager, and an actuator. In a preferred embodiment, the apparatus has a ring-shaped mounting body having a clearance hole therethrough. The apparatus is sliadably and rotatably mounted on a cylindrical rod through the clearance hole such that the apparatus is slidably rotatable along the length of the cylindrical rod. In operation, the engager is positioned in physical contact with the PC board in a notch in the board such that when a force is applied to the actuator, the engager is effected to urge the board to move in the direction of the force.
