摘要:
An improvement in garage door tracks which includes placing an inwardly pressed hem on the distal ends of the sections of track which surround the gap by which wheels from a garage door are placed into a track chamber. The hems on the distal end provide increased strength and a safer smoother edge. The inward hemming also does not interfere with the roller wheels of the garage door. This further solves the problem of track failure and bulge or crimping and causes less stress on the garage door track. A further innovation is to have strengthening ribs at different locations on the garage door track to provide further strength to the garage door track. A further innovation is to provide strengthening ribs at different locations on the garage door track to provide further strength to the garage door track.
