About us
It all began when L.A Macklanburg and his wife moved to their new Oklahoma City home in 1919. Prompted by the need to keep cold winter air and summer dust and dirt out, L.A. Macklanburg built the first weatherstripping in order to keep the elements from coming under his front door. Seeing an opportunity, he built a brass-folding hand-crank weatherstrip machine and took it to the Oklahoma State Fair in early July 1920, and thus a new entity was born.
