The distinction between a cramp folder and a pan break is primarily based on their design features, specifically the presence of feet on the pan break. A cramp folder uses clamps to hold the workpiece securely during the folding process, relying on manual or mechanical manipulation. In contrast, a pan break typically has feet that allow it to be anchored to a surface for stability and support, providing better leverage and control while folding larger sheets of metal or other materials.

The presence of feet on the pan break enhances stability and accuracy during operations, allowing for more precise bends in materials. This design feature differentiates it from the cramp folder, which does not typically have this characteristic.

Other options, like the construction material of the folders, weight capacity, and the length of the folding area, may vary between different models and manufacturers but do not fundamentally differentiate between the two types of equipment. The unique design aspect of the pan break is what makes it distinct in terms of functionality and operation.
