Armourwood Door Jambs come with standard widths to match the thickness of CHB walls. Although they are suitable for door systems in any space—interior or exterior, residential or commercial—due to their versatility, aesthetic appeal, and functionality, Armourwood Door Jambs are ideal for wet areas such as toilets, since Armourwood is protected against rotting or decaying fungus. Armourwood Door Jambs come in a set of 1 horizontal header and 2 vertical legs, available in standard sizes.
