Pressure from clamps can cause unpleasant marks on your carbon, NCR, and other paper products. This is where the magnetic clamp pad comes in. This durable foam pad laminated to a rubberized magnetic foundation will prevent any hideous marks caused by clamp pressure. It is recommended that a clamp plate should be used along with the clamp pad for further protection. At 15” in length, these clamp pads comes with 2 pads per package and can be connected magnetically for wider paper cutters.
