Abstract: A clip operable to secure panels of sheet material includes a generally H-shaped unit having pair of opposed arms separated by a central beam forming a pair of aligned receptacles, each operable to receive a panel therein. At least one of the arms includes biasing members operable to apply pressure to the panels inserted into the receptacles. The clip secures adjacent panels together in edge-to-edge orientation such that the panels are coplanar. Panels utilized with the clip include sheets of building material such as plywood, drywall, and roofing materials.
