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.

Threshold for door with sidelites on both sides. High quality threshold available in aluminum mill or bronze finish. Fits in-swing doors (door swings into the home). Perfect for replacing or upgrading an existing threshold that has rotted, cracked, or deteriorated.

Threshold is pre-notched for mull posts and comes with sidelite adapters installed. This greatly helps with the assembly of door systems with sidelite units.
