010 mm measurement range with a dial indicator and 0.01 mm accuracy enables precise cutting control for consistent results. Wide compatibility with 3/8 x 3/4 inch Tslot tracks and an adjustable length from 1.5 to 6.4 inches covers common track setups in workshops and fab shops. User friendly design features adjustable scales that simplify alignment, helping you set up cuts quickly and reproduce them reliably. Sturdy construction combines aluminum alloy and brass for durability, rigidity, and longlasting performance in daily use. Use scenarios Woodworking: position and align router fences or stop blocks on a Tslot track to achieve repeatable cut depths and precise miters. Metal fabrication: set up clamps or fixtures along Tslot tracks, enabling accurate placement of parts and consistent machining steps. DIY/multipurpose jigs: build and adjust precision jigs on modular workstations, ensuring repeatable positioning for repetitive tasks.
