Exterior Head Jamb (Stain Grade Mahogany)

Head jamb for exterior doors. Solid mahogany construction provides unparalleled durability, stability, and ease of installation. Stain grade matches our unfinished mahogany doors.

Key Specifications:

• Designed for exterior doors 1 3/4" thick
• Width:
• Single doors (add 1/4" to door slab width): jambs intended for use with standard steel and fiberglass exterior doors that measure 1/4" less than the head jamb actual width. For example, a 36.0" head jamb will work with a nominal "3/0" or "36" door slab that actually measures 35.75" in width. If you have a door slab that measures, for example, 36.0" wide, then you will need to purchase a 38" head jamb and cut it down to 36.25"
• Double doors (add 1" to combined width of slabs): 60.5" head jamb fits double 29.75" width doors (nominal 30" or 2/6 with a .75" astragal in between), 64.5" is for double 31.75" doors (nominal 32" or 2/8 with a .75" astragal in between), 68.5" is for double 33.75" doors (nominal 34" or 2/10 with a .75" astragal in between), and 72.5" is for double 35.75" doors (nominal 36" or 3/0 with a .75" astragal in between)
• Sidelites (add 1/8" to door slab width): jambs for use with standard steel and fiberglass sidelite panels should measure about 1/8" wider than the panel width, to provide 1/16" space on either side of the panel
• If you are unsure what width jamb you need, please purchase one with some extra width and trim on job site
• Depth: Select 4 9/16" or 6 9/16"
• 4 9/16" are standard depth jambs for use with typical (2x4) construction
