The splinter guard prevents the edges from tearing out even during angled cuts and allows for precise placement of the guide rail at the score line. To ensure this over time, it must be replaced regularly. The tear-free cut is achieved by the rubber lip, which presses the material directly down at the cutting edge, minimizing tear-out. Since the splinter guard is cut during the first use, it reflects the exact cutting edge, allowing for precise alignment at the score line. The replacement splinter guard is self-adhesive and can be easily trimmed. It is suitable for the guide rails FS, FS/2, and FSK. Transparent.
