ABSTRACT:
A cover mountable on a support frame for protecting a frangible item mounted within the frame is disclosed. The cover has first and second cover portions engaging the frame on opposite sides of the item. A hinge connects first ends of the covers together and a releasable fastener connects the other ends. Fingers extend from one or both of the cover portions toward the opposite cover portion and are positioned in spaced relation to the ends of the cover portions. The fingers and the ends of the cover portions define spaces at opposite ends of the cover which receive and engage portions of the support frame. The fingers are in spaced relation to one another and define a space between them for receiving the frangible item. The fingers are sized and spaced so that they transfer any force on the cover to the frame exclusively. The covers have an arcuate shape to provide increased stiffness.
