Exterior Head Jamb (Primed Poplar)

Head jamb for exterior doors. Solid poplar construction provides unparalleled durability, stability, and ease of installation.

Key Specifications:

• Designed for exterior doors 1 3/4" thick
• Width (add 1/4" to door slab width): Select 24", 26", 28", 30", 32", 34", 36", 38", 40", 42", 48", 60.5", 64.5", 68.5", or 72.5" (actual head jamb 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
