Clinch-On uses ABS (Acrylonitrile Butadiene Styrene) to manufacture its highly pliable and impact (dent) resistant plastic corner bead profiles. Clinch-On uses ABS rather than PVC (Polyvinyl Chloride) because a fire will cause PVC to form hydrochloric acid fumes, which are a serious and deadly hazard. ABS is environmentally safer and gives you better mud and paint adhesion, increased flexibility and durability, greater resiliency and improved flange crack resistance from stapling and nailing. Our intricate pattern of holes on the flanges of the corner bead allows the joint compound to penetrate through the flanges to the drywall and gives you a superior joint compound adhesion.

Clinch-On 1-1/4” flange ABS square corner bead with wide flanges and numerous perforations provides a liberal space for installation and ensures great joint compound adhesion.
