Luickly and efficiently join walk along track pieces together using the M 140 Track Splice and our M140 Track Punch. The M 140 Track Punch places the punch die in the exact location required by sliding the slot in the punch into the end of the top rail of the track until the track and punch meet firmly. Then squeeze the handles together to punch the 11/32" diameter hole. The hand held and operated punch provides more than a ton of punching force. The light weight punch can be used on the ground or in the grid.
