ABSTRACT:
The present invention relates to a strap tightening tool adapted to be used with straps of a variety of thicknesses including relatively thin metallic straps and thicker polymeric straps. The tool includes a spring biased pawl having two or more sets of teeth, the teeth of each set being offset from the pivot point of the pawl by varying distances so as to enable an appropriate set of teeth to clamp straps in accordance with the thickness thereof. The device may include a guide to extend between the pulling mechanism and the buckle of the strap to assure that the strap emerges from the buckle at an exit angle essentially parallel to the passage through the buckle.
