A ceiling panel installation support includes a rectangular tubular cushioned panel rest which during operation conveniently temporarily holds a ceiling panel, such as a sheet rock panel, up against an overhead ceiling structure while the panel is being secured in place by permanent attachment to the overhead structure by nails or screws or other fastening means. In preparing the present ceiling panel installation support for shipment, for storage or for carrying from one job site to another, the rectangular tubular cushioned panel rest is easily detached from its operating position at the upper end of the upright elongated, spring-biased, releasable-clutch-controlled jacking assembly. Then, this tubular panel rest is placed in telescoping relationship around the jacking assembly as a temporary housing for providing a compact and unified easily carried or stored package of components. A number of additional enhanced features are described in relation to the sheetrock support device disclosed and claimed in Patent No. 4,733,844, issued on March 29, 1988.
