ABSTRACT:
A vertically adjustable threshold member or bar is shipped in a down position and is adjusted upwardly at installation by attached shouldered leveling screws engaging within flared T-nuts of base or sub-structue. A compressible seal is interposed between the outer longitudinal edge of the adjustable threshold member and an extruded metal sill. The outer longitudinal edge of the threshold member is beveled slightly for increasing pressure on seal as threshold member is raised.
