Clinch-On “L” square corner bead trim was designed to fulfill two drywall trim needs. First, our “L” square trim was designed for drywall that abuts a suspended ceiling and secondarily it was designed as a wood reveal for window and door jambs. Our “L” square trim can be used where drywall abuts suspended ceilings, plaster, beams, wood, masonry or concrete. Clinch-On manufactures “L” profiles for a wide variety of installation requirements (1/4", 3/8", 1/2", 5/8", 3/4", 1" and 1-1/4" flanges). Our proprietary electro galvanized steel coating gives our “L” square trim a dark (dull) appearance and superior adhesion qualities compared to shiny hot dipped galvanized steel.
