Abstract: A poster gripping extrusion device for the close-in maintenance and rigid support of a flexible sheet of display material. The device includes an elongated planar base having a first or distal edge and a proximal or second edge defining a width of said base. A leg extends parallel to the base, the leg having a distal edge and a proximal edge, and only a single web or bridging portion extending between the second edge and the proximal edge of the leg to provide compactness to the device. A pivotable clamp extends from the distal edge of the leg, the clamp providing a first and a second line of contact between the clamp and the base to securely hold a sheet of material therebetween. The clamp has a distalmost edge which extends beyond the distalmost edge of the base portion of the device, to permit ease of manipulation of the device in “close-in” locations.

Abstract: Lightweight snap-together multi-sided hanging display signs which include upper and lower frames, each including at least three panel clamps which are interconnected at their ends with interlocking bracket and clip components in which the ends of pairs of vertical clamps are also seated.
