What are the removable bars on a box and pan brake called?

• A. Clamps
• B. Fingers
• C. Guides
• D. Ribs

Answer: (B)

On a box and pan brake, the bars you can remove and move to shape the formed pocket are called fingers. They sit across the bed and define the opening that shapes the sides of the box or pan; by adding, removing, or rearranging them you set the width and depth of the bend, which is essential for creating the desired box or pan geometry. Clamps are the hold-downs that secure the sheet during bending, guides are used to align the sheet, and ribs are structural features on a part or the brake. The fingers are the adjustable forming elements, which is why they’re the correct term here.
