Every single exterior door unit has a sill or a threshold, and those terms are interchangeable.
Some sills are wood, some are composite, and the cap is usually adjustable.
Here is the smart part most people miss.
At Magbee Contractors Supply, they add a sill cover, or sill protector, on top during construction.
People walk over that threshold a million times on a jobsite.
That cover keeps it from getting scuffed, scratched, or destroyed before the home is even done.
It is a small detail that saves the whole door.
