Sigma Series 4 Green Laser — See the Cut Line, Skip the Re-Measuring Measuring and re-checking every tile before you score eats time on a production run. The Sigma Series 4 green laser projects a bright, visible guide line that shows exactly where the cut will fall, so you align the tile to the line and score — no second-guessing. Green is easier to see than red on most surfaces, which keeps you fast even in bright jobsite light. It mounts to compatible Series 4 cutters and is built for large-format tile and repeated, production-style cuts where the time savings add up fast. Detailed fitting instructions are included so it goes on cleanly. Why Tile Pros Choose It See the cut line: Projects a visible guide showing the scoring path Less measuring: Align to the line instead of re-checking every tile Bright and clear: Green laser reads well on most surfaces Fits Series 4: Mounts to compatible Sigma Series 4 cutters Built for production: Speeds large-format and repeat cuts Easy install: Detailed fitting instructions included Pro tip: Check the laser against an actual scored line when you mount it and re-confirm after rough transport — a guide line is only useful if it matches the wheel. Nudge it back if it drifts.
