ABSTRACT:
The device is based on using a thrust bolt in a modified C-clamp design to push a pressure plate to pry apart two intersecting flanges of a profile. The device is primarily used for on-boat repairing of aluminum extrusion profile boat toe rails that have segments of their vertical flanges crushed inward. It has utility for bending any flanges apart that are greater than 20 and less than 160 degrees apart to start with. It has utility for bending flanges apart that are made from any material, such as metal, that has an elastic limit and enough plastic flow to permanently bend without rupture.
