A stiffener device for use in moving a truss is disclosed. A crane lift cable is attached to a spreader bar. Two lines from the spreader bar attach to the truss to move the truss using a crane. A stiffener body attachable to the truss by brackets allows the stiffener body to hang on the bottom chord of the truss. The stiffener body provides a significantly increased resistance to bending along the length of the truss. This stiffening prevents bending and flexing of the truss which can reduce the numbers of damaged trusses that can occur when setting trusses to a building structure. |
