Abstract:
1. A wall strap tensioner for tensioning a wall strap of a metal wall, comprising: a. first and second links pivotally connected together; b. a fastener secured to each of the first and second links for fastening to the wall strap; c. a flexible cable; d. a connector for connecting to the flexible cable; e. a handle pivotally connected to the connector and movable between first and second positions; f. a connecting link extending 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; g. a spring associated with the third and fourth links and which is operative to bias the third and fourth links towards the retracted position; and h. wherein as the handle moves from the first and second position, the effective length of the tensioner is decreased and wherein the spring applies a biasing force as the third and fourth links tend to move from the retracted position to the extended position, and wherein as the effective length of the tensioner is reduced, the wall strap is tensioned.
