The Spec Tools Bending Brake, No. BRB-100, is a patented fabricators hand-held bending brake , for accurate bending of sheet metal strip material for brackets. A duckbill clamping plier, fitted with a pivoting bending jaw, it handles metal widths to 3 inches in thin materials, down to 3/4 inch in gauges up to 5/64″ thick. This tool is especially useful for making pattern brackets and fabricating intricately shaped strap material for metal-mounting brackets. A reversible jaw provides extra leverage to create tight Z-bends with the jaw mounted at 90 degrees. Users can also dismount the tool, flip it over and remount the jaw straight off for maximum hand leverage on thick materials like muffler brackets and accessory mounts.
