ABSTRACT:
A jig for holding planar sheet material during installation. The device includes a channel section provided with captively held nail members for temporarily attaching the jig to a substructure, e.g. wall studs. The channel section further has a groove along an interior wall surface for receiving an interchangeable frictional holding strip. The intersection of a second interior wall and bottom surface forms an inclined wedging surface. An edge of the sheet material is placed within the channel and is grippingly engaged by the coaction of the frictional holding strip and the wedging surface. The sheet material is angularly supported resting against the substructure and can then be nailed in place.
