Heavy-duty Imperial 464-FH tubing bender is designed to accurately bend tubing of stainless steel and other tough metals, from 1/4 to 1/2 in. OD, up to 180 deg. Its Roto-Lok releasing collar and indexing handle allow it to bend tubing up to 90 deg, rotate and lock in a new position, and bend the tubing another 90 deg. A two-stage design prevents crossed handles on largest bends.
