M140 Track Stop for M140 Track. Two CNC machined 1/4-inch × 1-inch aluminum flat bars with contours that match the curviture of the M140 Curtain Carrier, so as not to “ding” the carrier wheel. The rear bar is threaded for a 5/16" socket head screw to fasten the track stop to the track without needing a nut. The M140 Track Punch will quickly and efficiently add a hole to mount the M140 Track Stop.
