A finger brake, also called a box-and-pan brake, is used for making bends in sheet metal. The brake consists of a flat surface onto which the material is placed, and a clamping bar which locks down to hold the material firmly during the bend. The clamping bar consists of a series of removable metal fingers. These fingers may be removed and rearranged to permit bending of restricted areas of a piece of sheet metal or of already partially formed pieces. The front plate of the machine is hinged and may be lifted, forcing the material extended over a straight edge to bend to follow the plate. Bends can be made up to any angle with a practical limit of about 120 degrees.
The Jet BP-1648H has a maximum bending capacity of 16 gauge steel.
