ABSTRACT:
A hinged retaining bar which engages the otherwise free edges of circuit cards when in position in a card file has an engagement face provided with slots filled with a resilient material. The resilient material provides elastic engagement with the edge of each card whereas the slot edges provide rigid restraint against lateral motion to prevent vibrational damage to the card and abrasive wear of the resilient material. A unique gripping action is attained through a particular slot geometry.
