CG Hardwood Molding's t-molding can connect floors of adjacent rooms, can be installed in doorways or they can be used to make the transition between two floors of the same thickness. All our moldings are treated with aluminum oxide for greater durability. This treatment also significantly slows yellowing and protects against UV rays. Its hybrid height allows the molding to be installed on floors as thin as 1/2" or as thick as 3/4".
