ABSTRACT:
An adjustable spacer and hanger apparatus is described which may be used to adjust the spacing between two utility pole crossarms and to support an electrical utility line on such crossarms. The adjustable spacer and hanger apparatus includes a pair of bracket members attached to a pair of spaced elongated support members such as utility pole crossarms. Each bracket member includes a threaded stud connector which engages the opposite ends of a rotatable hanger member positioned between such pair of bracket members. The spacing between the bracket members and the support members or crossarms is adjusted by rotation of the hanger member about the threaded connectors. The hanger member is provided with an aperture or fastening ring for attachment to the element being supported, such as one end of an insulator stack supporting an electrical utility line.
