With the Dewalt DWS5100-XJ rip guide, you make perfectly straight and consistent parallel cuts using your DCS577 circular saw. You eliminate the need to clamp separate straightedges or mark continuous chalk lines, saving valuable layout time during repetitive ripping tasks on sheet goods. The guide delivers a ripping capacity of up to 300 mm on the left side and up to 360 mm on the right side. Thanks to the permanent laser-etched markings, you can adjust your cutting dimensions quickly and accurately. Built from lightweight and durable aluminum, it folds down easily for compact storage and convenient jobsite transport.
