The FrameAll Drywall Grid now has knurled ridges along the length of the cross tee. The new feature improves screw grab and reduces screw spin-out during board installation. In addition to improving handling, the knurled ridges also stiffen the tees. When screwing tee to tee, there is no need to C-clamp the tees together for a quick, clean screw grab through both tees. Knurled ridges are one of several standard features that provide a performance advantage enabling installers to work faster and easier. FrameAll products carry a “Made in the USA” label, indicating the material is sourced and manufactured in the country. For more information, visit armstrongceilings.com.
