ABSTRACT:
A threshold cover, made of aluminum or similar material, which is retrofit over an existing door threshold by sizing the cover to exactly match the exposed portion of the existing threshold, and then attaching it directly over the threshold. The threshold cover preferably has a non-skid surface, and may have an internal flange of its vertical leg to mechanically interlock with the front edge of the threshold. The cover may be formed in two articulating parts to accommodate non-planar thresholds. Weep channels in the bottom surface cover serve to drain water which may get under the cover.
