3-1/2 CCM35 casing turns the edges of a door or window into part of the room's design. This trim frames the opening and covers the transition between the jamb and the surrounding wall.
For a modern look, keep the surrounding trim simple and let the profile's proportions define the opening. Coordinate it with clean-lined baseboard, and consider a compatible backband when you want added depth around the frame.
Measure each opening and plan the casing reveal before cutting. Confirm thickness, width, and piece length. Leg pieces must be long enough for the full assembly, including the chosen corner joint.
