Abstract: A tool for relieving strain on a plurality of serially connected elements, such as, electrical insulators in a strong of insulators. The tool has two separate rachetable turnbuckles that each actuate a pair of opposite-hand jack screws. A strain diverter collar having a set of strain diverter halves is clamped around an electrical insulator and is releasably secured to corresponding jack screws actuated by the rachetable turnbuckles. In one embodiment, another set of strain diverter halves is clamped around another electrical insulator and is releasably secured to the other corresponding jack screws so that racheting of the turnbuckles in one direction relieves strain on the insulators and in the other direction reapplies strain on the insulators.
