Aluminium Accurate measurements Our aluminum adjustment blocks come in lengths of 3 inches and 5 inches. They provide precise fractional inch options including 1/16, 3/32, 1/8, 5/32, 3/16, 7/32, and 1/4 inches. When combined with rods, you can set up to 100 different measurements. Stack adjustment bars to cover multiple variations or sizes, or use them individually for quick work and measurements. No damage measurement Aluminium construction with a black anodized finish provides a softer contact surface than router bits. This reduces the risk of damaging carbide cutters, offering better protection for router bits and saws. Laser engraved marks Easy to read and accurate engraved labels are on the aluminium stand. You can quickly start work on your table without guesswork and measurement errors. Easy to use Different size height adjustment blocks make it easy to adjust the height of fences, blades and other knives as needed, faster and more accurately than using a ruler. Use scenarios - Router table setup: precisely set blade height and fence alignment for accurate dadoes, grooves, and crosscuts with repeatable results. - Saw and jig adjustments: quickly configure fence and blade heights when changing cuts or substrates, improving setup time and consistency. - Multi-piece projects: stack blocks to reproduce exact measurements across multiple pieces, ensuring uniform dimensions throughout the run.
