Here's a new approach to flanging patch panel areas. This tool uses two gear-driven rollers, which can be adjusted to accommodate steel or aluminum from 24 to 18 gauge. To turn the rollers, simply attach your ratchet wrench and 5/8in. socket. The hex drive turns a gear that interlocks with the rollers. Very smooth action creates a tight-stepped flange. Made from drop-forged steel with heat treated gears. Handles are 11in. long. Made in England.
