CS SquareStop detail is a design option to create a square finish with no architrave or negative detail around the door frame. This design option either has the plaster butting into the timber jamb and the join is taped set and finished by the plasterers, otherwise a steel reveal angle can be supplied and fitted over the return corner by the plasterers on site for added strength and duraility (recommended).  

Please feel free to contact our customer service staff for more detailed information.
