STClip is a patent pending steel stud clip that holds a dimensional 2x4 and 2x6 wall while achieving sound termination ratings > 50 in the field. Sound rated walls are one of the fastest growing categories of wall construction throughout the U.S. and becoming a code requirement in several types of construction. Most sound walls are built to laboratory specifications with lesser results in the field. STClip is tested by accredited Element Testing Group, St. Paul, MN to achieve equal field and laboratory testing results.
STClip creates a thinner wall to maximize useable space and eliminate custom sized jambs for window / door openings and custom fixtures compared to thicker sound wall assemblies.
STClip saves installation costs with a standardized attachment pattern, simple installation, and no mechanical fasteners on steel studs, eliminating the risk of short circuiting. STClip simply snaps into place on steel studs.
STClip creates higher STC ratings with less labor, and less wall thickness than competing systems. It simply stops sound in its tracks.
STClip can be used on new construction and renovations. It is not required to be used with Eliminator Track, however it can be used in combination.
Eliminator Track(R) is an innovative, patented product that revolutionizes the entire build-out process for both new construction and remodel projects. Eliminator Track(R) replaces the standard top track in non-load bearing walls in building areas where ceiling grids have been installed. Eliminator Track(R) reduces the time required for ceiling lay-out, carpeting and the framing, drywall and finishing of non-load bearing interior walls.
Eliminator Track(R) provides a clean, attractive appearance at the ceiling-wall intersection without the need to frame individual walls prior to installation of the ceiling grid. Eliminator Track(R) allows steel studs to simply be snap-locked into position.
