Abstract: A connector fixture for joining a first structural member to a second structural member. The second structural member includes a central bore and a pair of lug receiving apertures disposed at a predetermined distance on opposite sides of the central bore. The first structural member includes a central bore adapted to register with the central bore of the second structural member and in addition has a pair of outwardly extending lugs which register with and are received in the lug receiving apertures in the second structural member, thereby properly positioning the first and second structural members relative to each other. A connector, such as a bolt and nut, is then inserted through the central bore of the first and second structural members to clamp the members together.
