A weather bar is a water and draught excluder used for exterior doors. It can also be used to provide protection from the elements and wind-driven rain. When correctly installed, weather bars typically will not affect the operation of standard deadbolts or other locking mechanisms. Our XL joinery oak weather bar has been precision cut to size to fit snugly into most standard sized exterior door frames. It is easy to install, looks great and provides long term protection against the elements and rainwater.
