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

• 4 9/16″ are standard depth jambs for use with typical (2×4) construction
