Specifically designed to fit the needs of shops with a volume of 20 gauge work . but equally valuable in larger shops as a companion to the Lockformer® 16 gauge capacity Speednotch. The back gauge bar holding notching heads has a direct-reading tape to provide simple, fast set-up. The locking handle allows adjustment of notch depth and end notch pattern. And individual head control lets you notch single-piece or two-piece duct. Nice unit, we will skid at no charge to save freight charges.
