The WEC is a tensioning device for joining construction elements and beams. Together with the optional WECSA accessory, the tool is an ideal aid for tensioning wind braces. The double trapezoidal threaded spindle in conjunction with the high-quality ratchet ensures twice as fast and yet effortless tensioning compared to a standard single-run threaded spindle. The hand-forged, robust hooks guarantee secure installation and a perfect hold in the wood. The WECSA panicle strip holder is screwed onto the spindle with a right-hand thread instead of a hook. An eccentric clamping device reliably holds panicle strips up to 80 mm wide, enabling hands-free attachment of the panicle strips to the wooden structure.
