Dual extrusion snap closed ceiling sign hanger
Abstract:
A dual extrusion hinged sign hanger hangs from the ceiling and holds signs, banners, posters, and any other sheet type of display material. Display material can be easily changed within a smooth non-damaging holder portion which opens for free non-friction insertion of the display material. The closure has flexible tabs on one side and a smooth flexible curved surface to hold the display material against the tabs. The closure acts perpendicularly to the display material with a snap together closure that does not come in contact with the display material.
