Casing

Dunbarton frames and casing are designed to work together to offer the best commercial, industrial, and multi-family package. We offer casing in steel, aluminum, and S56 Colonial. However, you also have the option to use any wood trim you prefer. Additionally, all trims are available in our standard colors or custom color-matched to meet your job specifications!

Dunbarton provides casing for our frames in three styles:

Steel Casing: 1-1/2″ width

Our steel casing is 1-1/2″ is standard on all RediFrame products except Kerf RediFlex.

The aluminum casing is an extruded casing designed with modern, sculpted lines in durable prefinished aluminum.

S56 True Colonial Casing: 2-1/4″ width

Casing Installation Attachments

Casing Corner Clips

Dunbarton’s Casing Corner Clips are designed to hide surface distortion and gaps. They are also designed to allow the casing to be removable in case of any changes. When installing casing on RediFrame and RediFlex frames, the supplied clips are designed to snap in place into both ends of the header casing. After installed, the clips help ensure the proper alignment of the miter between the header casing and jamb casing on our steel, aluminum, and S56 Colonial casing.

Note: The RediFrame system does not require crimping to hold the clip in place.  The combination of the casing, frame lance, and clip design also makes sure the casing does not rattle during the operation of the door.

Thresholds

The purpose of a threshold is to close the gap between the bottom of a door and the floor. Thresholds are used with door bottoms and weatherstripping to seal the opening, preventing air, rain, and snow from entering.  Dunbarton has four standard styles with two extenders for the fixed inswing, with other options available.
