An apparatus for holding sheet material and bulk objects concurrently is disclosed. Each of a pair of parallel rectangular plates attaches to a rectangular, opposed block with hand wheels. Hand wheel threaded studs extend downwards through said block into the longitudinal slot of a rectangular bar and fasten into nuts seated at base of said slot. Said rectangular bars radically attach to a corner. Engagement of hand wheels applies and releases force against slot both locking block and plate assembly and enabling said assembly to travel along said slot; travel in slots towards said corner pushes plates against one another yielding holding pressure. Slip resistant backing of bar and plate assembly stabilizes device on contact with any substantial, flat surface. A demountable column attaches to said corner and supports a rigid panel, and demountable shelf with holding attachments by means of stud insertion into modular recesses. |
