Includes a #10 x 1" machine screw to be used in place of the "star bolt" to jamb the upper telescopic shaft (as you screw the tool onto the shaft it will push the bolt against the inner rod which will jamb the telescopic movement)
Make sure the telescopic shaft is in far enough to allow the C clip to slide into the groove in the main shaft. Once the C clip is in place the telescopic shaft will now have limited travel.
