The removable bars on a box and pan brake are called?

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

Answer: (D)

The removable bars are called fingers. On a box and pan brake, these fingers span the bed and can be removed or rearranged to set the width and shape of the bend. When in place, they support the sheet along the bend line and allow for clean, uniform flanges as you form boxes or pans. They’re named fingers because they function like adjustable fingers across the bed. Other terms describe different parts: clamps hold the sheet in place, ribs are reinforcing ridges, and guides help with alignment, but the removable bars used to shape the sides are the fingers.
