An Introduction to Superbolt Multi-Jackbolt Technology

This video provides an introduction to the proven Superbolt multi-jackbolt technology, demonstrating how it works, and illustrating how Superbolt tensioners can benefit your application. Because only hand tools are needed for installation and removal of any size tensioner, worker safety is greatly increased versus other bolting methods.
