Chance's Anchor Expanding (Buster) Bar simplifies the job of expanding anchors by distributing the weight of the bar evenly around the anchor rod to reduce handle vibration. The hook of the expanding and tamping bar wraps around the anchor rod to keep the expanding head from slipping off the anchor top plate. This tool is also effectly used for tamping in soil above the installed anchor. The base casting is attached directly to the fiberglass handle.
