TightStrap®

TightStrap Tool

TightStrap® is a unique device used to tension (tighten) flat strap in the field. The pre-tensioning of a shear wall flat strap provides a means to ensure the shear wall will perform as designed. It is important that the flat straps are as tight as possible when installed to achieve optimal system performance. Use TightStrap to improve structural performance of a shear wall by removing "waviness" or "bowing" prior to fastening.

Product Information

TightStrap is designed to be used in both StiffWall® and generic flat strap shear walls. The StiffWall SW-S Strap Track contains pre-drilled guide holes for quick attachment of TightStrap's "Z" fittings (See Installation Step 2). If the guide holes are not available in generic flat strap shear wall assemblies, use a #12 screw to create holes for the "Z" fittings.

It is preferable to tighten the flat straps after applyiing some vertical load (own weight) on top of the shear wall panel.
