Phillips gripSTIK Flat L-Tear Strip provides a clean line at a variety of wallboard intersections. A one-size-fits-all product, the Flat L-Tear Strip is used where a straight edge is needed and there is not enough room at the intersection for the leg. The tear off strip provides a protective edge and a guide for drywall finishing knives. Once joint compound is applied, finished and painted, the tear off strip is removed to form a clean, crisp edge. This product features deeply knurled mud anchors, many perforations, and specially textured surface to provide superior paint and joint compound adhesion.
