Replacement Telfon Cutter Protection strip for the Graphtec CE5000 Series cutters.
The cutter protection strip runs the width of the cutter underneath the blade track. Its purpose is to protect the blade from damage should the cutting depth be set too deep.
The protection strip should be replaced when it has a deep groove cut into it from the blade. If it isn't replaced, the blade will no longer cut at an even depth across the width of the vinyl/media resulting in poor cut quality.
