ABSTRACT:
An apparatus for attaching external stores or loads on a thin walled pole includes a first, open ended and externally threaded hollow sleeve defining a shoulder at one end, and a second, open ended and internally threaded hollow sleeve. An elliptical disk mounted to one end of the second sleeve defines a second shoulder. An other end of the first sleeve is threadable in an other end of the second sleeve to form a hollow sleeve assembly of variable length. The elliptical disk has an elliptical projection which fits in an elliptical hole of a thin walled pole when the hollow sleeve assembly is fitted therein. By using an external tool to relatively rotate the first and second hollow sleeves, one can tighten the hollow sleeve assembly to provide an expansive prestress and support for a bolt which passes through the hollow sleeve assembly for attachment of stores or loads.
