J-Tabbed Track is used at the floor and ceiling in shaftwall assemblies. CT studs and gypsum shaftliner panels are friction fit between the top and bottom J-Tabbed Track. J-Tabbed Tracks have unequal legs. The longer leg (available in 2-1/4" and 3") is installed against the shaft. The leg provides a backstop for easy installation of the liner panel. Three-inch leg track is typically used as a jamb strut around closure details, including duct and door openings, abutments and intersections.
