| Material | Cast iron |

Product overview
What it does, and where it fits.
The bend is used to build frames on vertical tubes. It is the corner of the rectangle: one socket takes the vertical member, the other takes a horizontal, and the frame is closed by repeating it at each corner.
Cast iron, slidable, fixed with grub screws at the required position — so the frame height is set on site and can be changed later without cutting anything.
Four sizes cover 25 to 50 NB, with H and H1 growing from 50/55 mm to 85/95 mm as the tube gets larger.
