ABSTRACT:
A tool is disclosed for installing a glazing strip in the corner defined by two mutually perpendicular surfaces. The strip comprises extruded polyvinylchloride plastic having a cross sectional shape such that a glazing compound is provided in a central cavity to be extruded through a slot covered temporarily by a paper layer which covers the slit and one entire face of the plastic strip itself so that the strip can be conveniently provided on a roll or the like. The tool provides convenient means for stripping the paper layer from the face of the strip such that it can be first laid in the corner in an initial position by sliding the tool along the plastic strip and simultaneously peeling the paper backing therefrom. The strip is passed through an elongated cavity in the front side of the tool, which cavity exposes a major portion of the strip face so that the paper can be stripped entirely free of the plastic strip if desired. Inturned lips hold the plastic strip in the elongated cavity and a projecting nose portion of the tool provides a radius for the strip to facilitate both the peeling of the paper, and laying of the strip in the corner. The opposite end portion of the tool defines a blunt contoured end portion for pressing the strip after it has been so inserted in a corner to extrude the glazing compound through the slot and into the space between the inner face of the strip and the corner being treated.
