Framing and Jamb

Our pre-hung entry door systems are composed of the finest materials for ease of installation and long-lasting beauty. With just the rough opening dimensions and product specifications, we will build your entry door to fit like a glove – even complex doors with curved jambs and arched sidelites.

We offer standard and custom jamb widths along with a variety of thresholds, including ADA-compliant thresholds. All door designs are available as single or paired, out-swing or in-swing, with both right or left hinging. Inquire about our complementary pre-hung interior doors.

Jamb Information

Jamb Information

  • As specified, our doors are shipped pre-hung in both standard size and custom jamb widths. The jamb wood species matches the door if it will be stained.  If the door is Western Red Cedar than an African Mahogany Jamb will be used because cedar is too soft for jamb purposes. If primed, the jamb is typically made of Douglas Fir or mahogany.
  • The rough opening for the jamb is equal to the door width + 2-1/4” and door height + 2-1/2”.
  • Pre-hung doors and their jambs are mortised for three (3) 4-1/2" x 4-1/2" hinges with square corners.  We offer standard Dull Brass or Oil Rubbed Bronze hinges. If the door is more than 7' high, four (4) hinges are provided. We can mortise for any specified hinge.
  • We offer several options for casing and exterior brick mould, including both standard selections and profiles customized for your design.
