How we estimate

Most in-stock items that need no shop work leave our warehouse the same or next business day. Ordering by 12 pm Eastern, Monday to Friday, gives yours the best chance of shipping the same day.

Shop work starts once everything is in stock: trimming, cutting or prep takes 1 business day, finishing (priming, painting or staining) 1 to 3, and assembly, such as a prehung door system, 2 to 5. Out-of-stock items without a restock date usually ship in about 2 weeks, plus any shop work.

Ground parcels take 2 to 4 business days. Doors, sidelites and other large items go by freight: Priority Freight takes 2 to 5 business days and economy freight 7 to 15; you choose at checkout. Weekends and carrier holidays aren't counted. These are estimates, not guarantees.

One-piece head jamb for an exterior door with one sidelite, mortised for the mull post. Solid poplar construction provides unparalleled durability, stability, and ease of installation.

Built for the outdoors

  • Treated hardwood, not a composite or plastic, so it cuts, nails and paints like real wood
  • Treated top to bottom to resist rot and decay
  • Water-resistant factory primer gives paint a smooth, even base
  • Won't warp, swell or shrink like composites, and won't turn brittle in the cold like PVC

Key Specifications:

  • For one exterior door 1 3/4" thick with one sidelite, joined by a mull post (sold separately)
  • Length: (door slab width + 1/4") + (sidelite panel width + 1/8") + 1 1/2" mull post. Select your door slab width (29.75", 31.75", 33.75", 35.75" or 41.75"), then which side the sidelite is on viewed from the exterior and its panel width.
  • Sidelite widths: 9.875", 11.875" and 13.875" sidelite panels, or a 23.75" door slab used as a sidelite panel
  • Comes mortised for the mull post: 2 1/2" wide x 1/2" deep, centered on the 1 1/2" mull post (the mortise starts 3/8" short of the sidelite panel width, measured in from the sidelite end). The mortise is off-center, so left and right versions are different parts.
  • Need a different door or sidelite size? Contact us and we can cut one to order.
  • Depth: Select 4 9/16", 6 9/16", or 8 9/16"
    • 4 9/16" are standard depth jambs for typical (2x4) construction
    • 6 9/16" are extended depth jambs for (2x6) construction
    • 8 9/16" are oversize depth jambs that can be trimmed to fit thick walls (e.g., 2x8 construction, masonry walls)
