TightStrap^® is a unique device used to tension (tighten) flat strap in the field. Use TightStrap^® to improve structural performance of a shear wall by removing "waviness" or "bowing" prior to fastening.

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.

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.
