The handle has an open end wrench at its end. A movable jaw and adjusting nut complete the wrench. Some have part no. L320, and some have the PLANO trade mark molded in as well. It appears in parts catalogs for PLANO binders. A catalog page from CHICAGO HOUSE WRECKERS listed the remainder of the stock for sale. That company had also salvaged construction materials from the Chicago World's Fair. A similar malleable iron wrench marked 794 is 7 inches long.

Claim 1: "A ratchet wrench comprising: a ratchet head including a ratchet system for rotating a shank about an axis; a handle; a pin connecting said ratchet head and said handle, said connecting pin being aligned along an axis which is substantially parallel to the shank axis; said connecting pin extending through an orifice in one of said ratchet head and said handle, said one having said orifice being slidable between a locked position and an unlocked position on said connecting pin; in said unlocked position, said orifice being disposed about a portion of said connecting pin which is shaped to allow said one having said orifice to rotate about said connecting pin axis; and in said locked position, said orifice being disposed about a portion of said connecting pin which is shaped to engage said one having said orifice to prevent rotation thereof about said connecting pin axis." Postings in a "Garage Journal" thread noted Cole produced this design under "SUPERIOR TOOL COMPANY" and "SUPEIOR RATCHET AND TOOL CO.}, and licensed the design (along with 5,775,184) to Snap-On.
