The Chance Roller Link Stick is used to spread and hold conductors aside at midspan when relocating poles. It is applied to the conductor at the pole and pulled to position by a hand line attached to the butt ring. The handline should be secured by a temporarily installed screw anchor or other fixed object.

The tool is also used for measuring conductor-to-ground clearance by attaching a measuring tape or length of rope to the butt ring. Poles for Roller Link Sticks are 1-3/4 inches … rotating the pole closes the hook … leaving the head free to roll along the conductor.
