Thread the drop wire or distribution cable through the hook. A tree pruner handle is attached to the “F” Span Clamp by means of a special wrench. The clamp is then raised to strand height with the tree pruner handle and placed on the strand. Turn the pruner handle from the ground. This will activate a mechanical clamping action which will secure the clamp to the messenger strand. Once clamp is secured, remove pruning handle by rotating counter-clockwise.
