Your Series 4 cutter's measuring bar is what makes repeat cuts fast and exact. A worn or damaged bar costs you that precision — and slows down production work where every piece needs to match. These genuine Sigma replacement swivel measuring bars and guides (in inches) restore precise measurement and smooth positioning for repeatable cuts on your Series 4 machine.
Match the bar to your cutter: 90NB fits the 4BN and 4BU; 90NC fits the 4CN and 4CU; 90ND fits the 4DN and 4DU; and 90NE fits the 4EN and 4FN. Genuine Sigma parts that bring your cutter back to factory accuracy.
Pro tip: Confirm your Series 4 model before ordering so the bar matches the frame. Pair a fresh bar with a clean carriage and a good wheel and your cutter measures and scores like new.
