Aluminum Ruler Stop 39MM Precision Positioning Block for Technical Drafting and Measuring

Metal Scale Positioning Block Model 39MM A compact, hardened aluminum alloy positioning block designed for precise stops and repeatable measurements when used with standard steel rules and measuring guides. Key benefits Accurate and repeatable positioning for layout, marking, and machine setup, saving time on repetitive measurements. Durable corrosionresistant aluminum alloy construction that resists deformation under pressure for stable, longterm use. Nonfade graduations and an ergonomic profile that improve slip stability and maintain clear visibility of measurement markings in varying light. Compact design that integrates seamlessly with standard measuring rules to streamline workflow in workshops and labs. What it does Serves as a steel rule stop and positioning block to set exact offsets, limit travel, and provide consistent reference points during cutting, drilling, scribing, or inspection. Optimizes efficiency where repeatable dimensional control is required, such as machinery setup, material layout, and precision assembly. Compatibility and specifications Component material: Aluminum alloy Model 39MM size: 52 x 25 x 12 mm Suitable for ruler width: 35 to 39 mm Suitable for ruler thickness: up to 2.3 mm Performance features Hardened aluminum body resists deformation under clamping or pressure loads. Precise machining delivers millimeterlevel positioning accuracy. Nonfade graduations and ergonomic edges improve handling and visibility. Compact footprint integrates with standard rules without interfering with normal use. Practical use scenarios Metalworking: Use as a repeatable stop on a rule when marking or cutting sheet metal to ensure identical part dimensions across a run. Carpentry and joinery: Set accurate offsets for repeated cuts or mortise locations when using a marking rule or straightedge. Laboratory and inspection: Use as a reference stop for quick, repeatable measurements during component verification or fixture setup. Package contents 1 pcs Positioning Block Model 39MM Notes Please allow 1 to 2 cm measurement variation due to manual measurement. Product appearance may vary slightly from images because of differences in monitor displays. This positioning block is intended for users who require consistent, repeatable stops and reliable integration with standard measuring rules in fabrication, carpentry, and precision work.
