Reed Tubing Benders, in popular sizes, are ideal for bending soft metal tubes of copper, steel, stainless steel, and aluminum. The tubing benders should not, however, be used on extremely thin or hard-tempered material. All metal parts are chrome plated for corrosion resistance. Starting at a 90° angle, ergonomic round offset handles allow bends up to 180°. Calibrated angle markings appear every 15°, with separate gauge marks for right (R), left (L), and normal (O). TB3456 Quad Bender is ideal for plumbing and HVAC applications because there are four sizes in one tool.
