Abstract
A reversible threshold is provided for positioning beneath a door mounted in a door frame. The threshold includes a base and a riser which is removably connected to the base and provides a sealing surface for the bottom edge of the door. The riser has a sloped upper surface to carry water away from the door. The base can be placed in one orientation for an in-swing door mounting and another position for an out-swing door mounting. The riser is also reversible so that it can be placed with the top surface sloping away from the door when the base is in either orientation.
