This is a hand bender that allows you to make nice clean smooth bends in steel, aluminum, copper, and even stainless steel lines without kinking them.
This works on all lines ranging in diameter from 1/4" to 3/8"
Has markings to show what die to use for each size line and has a scale that shows what angle your are bending to which is great if you need to make multiple bends and repeat them.
The tool is made from forged aluminum with precision machined dies and bending surfaces.
