To make and break cable tool joints with circle jack (or howerver handle them).
Overall length around 65",
spanner size for around 4-1/2' to 5" wrench flats / squares.
Presumably American manufactured with carbon and/or alloy steels, but unsure if this is Acme, Spang, Gill Rock Drill, Ideco, Trident, Rampp, O.W.S. Co., Keystone or maybe another historical tooling manufacturer.
If you require thread protector(s) on tool joint(s) add another $15.
