Our PATENT PENDING spring rake design attaches to a fiberglass extension pole you already own. The 1 1/4 " male ferrule we use is all aluminum and fits most commercially available fiberglass extension poles. It attaches and detaches just like your Big Shot, pruning or saw head does. Store it in small lockers or even behind the seat. You can finally have a rake that isn't in the way, snagging other tools in those big tool storage lockers. On top of that because you attach it to extension poles, you now have a sturdy rake handle that fits the hand well, and is a longer reach than standard rake handles.
