Auto-Zip(TM) Stud Tensioners featuring the unique ZipNut® Double Zip(TM), cut the time it normally takes with conventional Tensioners. The time-savings is achieved because the new Tensioners “Zip On” and after tensioning “Zip Off” without any threading of the pulled bar, and are narrow enough to achieve 100 percent stud coverage. This provides one pass tensioning, virtually eliminating stud cross talk and stud load loss, which is common when using conventional Tensioners that do not allow 100 percent coverage. The technology also is being used in nuclear, pipeline construction and sub-sea markets. Several sizes are available with additional sizes being added on an as-needed basis.
