What is a water-return interlocking bronze threshold?

A water-return interlocking bronze threshold is designed for exterior wood doors where managing rain at the sill is especially important. The profile helps collect and direct water back toward the exterior while the J-hook creates the interlocking seal at the door bottom.

It is most useful when the opening is exposed to wind-driven rain and there is enough sill depth and door clearance for the deeper profile.
