Abstract
A wall strap tensioner for tensioning a wall strap of a metal wall. The wall strap tensioner includes first and second links pivotally connected together. A fastener is secured to each of the first and second links for engaging and fastening to the wall strap. Disposed about the opposite end of the tensioner is a flexible cable adapted to be secured to a portion of the metal wall. A connector connects to the flexible cable and a handle is pivotally connected to the connector and movable between first and second positions. A connecting link extends between the first and second links and the handle, the connecting link including third and fourth links that are movable with respect to each other and which are movable between retracted and extended positions. A spring extends around the third and fourth links and biases the third and fourth links towards an extended position.
