My house was built in 1955. The contractor installed 4.5" asymmetric oak thresholds on the side entries and a 5.5" asymmetric threshold on the front entry. I would like to replace them. They are worn, checked at the ends, and badly discolored.
By asymmetric threshold I mean, for the 5.5", a profile (starting from the inside out) which is a ~1" rising transition to the under door portion (profile convex then concave), a 1.75" under door portion which pitches slightly to the outside for drainage, and a 2.75" outer falling transition, similar to the inner transition, but with a long down sloping flat section in between the curves.
Does anyone know of a source for such a threshold?
Thanks,
