- Size options: No.1 includes 1/16 in, 3/32 in, 5/32 in, 1/8 in; No.2 includes 1/4 in, 3/16 in, 5/16 in, 7/32 in; No.3 includes 11/32 in, 7/16 in, 15/32 in, 1/2 in; No.4 includes 23/32 in, 3/4 in, 7/8 in, 1 in. - Material: Made from high grade solid aluminum with distortion relief, precision ground and hardened for accurate, stable measurements. - Cross design: The setup block height gauge is cross shaped to support four height measurements, enabling quick transitions between different measurement needs. - Easy storage: Includes a plastic storage case for organized, protected storage and easy transportation. - Benefits and use cases: Provides four precise height references in a compact block, improving setup speed and accuracy for tooling, fixtures, and part inspection. Ideal for machining setups, fixture alignment, and quality control checks where repeatable height references are required. - Practical applications: - Set tool and workpiece heights quickly on milling machines or grinders. - Align work surfaces or vises in CNC or manual setups. - Verify consistent part heights during production QC or assembly.
