ABSTRACT:
A universal center hook is designed to be used with several office accessories for handling data media. The universal center hook comprises an elongated frame to which are pivotally joined a pair of side members. A selected accessory is captured between the frame and a side member when the side member is pivoted to a closed operative configuration wherein it lies parallel to and close to the frame. Hollow cylinders projecting from the frame sides align with and locate the accessories. The hollow cylinders cooperate with means in the side members to releasably lock the side member to the frame.
