Abstract
Abstract A molded plastic fixture holds an end of a telephone wire cord wound on a mandrel to retain the cord in position during subsequent heat processing. The mandrel fits into a bore in the fixture and an angled arm extending from one side holds a band spacer and strain relief member at the end of the cord. An opposite side of the fixture includes a channel to receive cords with no strain relief member. A manually adjustable screw clamps the end of the mandrel within the bore of the fixture.
