Does anyone know where I can get an adjustable door threshold that's 45 inches long? Every one I've seen online is 36" long, but we have to install one under each of 4 sets of French doors, and the space is about 45". I am assuming we'd have to custom order from a manufacturer, so I'm wondering if anyone knows which manufacturers might do that.

Thanks!

Hi neighbor! (we're on Cap. Hill in DC)
You rock! Thanks for the quick answer, as well as your earlier posts explaining how to install them.
I am assuming I just have to cut the 72-inch threshold down to the size I need.
Sooo grateful for your guidance!

Hi Mary,

Yes, that's correct. Note that extensions (for the width) are also available should you have a thick wall or wish to extend the threshold out underneath a storm door.
