Purpose and benefits Precision hole positioning: T-shaped rulers and a sliding ruler let you mark and drill exact hole locations, reducing mistakes and rework. Faster setup and consistent results: adjustable stops and a strong locking mechanism hold settings securely so repeated holes are identical each time. Durable accuracy for everyday or professional use: CNC machined aluminum construction with an anodized finish and engraved scales resists wear and keeps measurements reliable. Key features T-shaped rulers with flat edges for stable alignment and clean, repeatable layout. Clear gradations on both the main ruler and the slider for easy, accurate marking and measuring. Unique adjustable design and sliding ruler for precise control of hole placement, length and angle adjustments. CNC-machined aluminum alloy body with anodized surface to prevent corrosion and surface wear. Engraved scale for long-term legibility and measurement accuracy. Built-in high-precision spirit level to confirm horizontal and vertical alignment. Convenient calibration tool and robust locking mechanism to maintain set positions under load. Performance and accuracy Ensures both horizontal and vertical positioning accuracy for drilling and layout tasks. Strong locking and precise adjustment mechanism reduce drift during drilling, improving hole alignment and fit. Designed for repeated use without loss of measurement fidelity thanks to machined components and engraved markings. Material and construction CNC machined from aluminum alloy for stiffness and light weight. Anodized finish protects the surface and keeps scales readable over time. Flat, true edges provide secure contact against workpieces for accurate layout. Practical applications Cabinetry and hinge installation: accurately locate and align hinge screws or hardware mounting points across multiple doors and frames. Furniture joinery: set precise dowel, bolt, or pocket-hole positions for consistent joints and tight fits. On-site layout and light construction: verify and transfer horizontal and vertical positions for fixtures, trim, or small framing tasks. Why this tool matters Reduces layout errors and wasted material by making precise marking and drilling straightforward. Saves time when repeating identical holes or transferring measurements across parts. Built to hold calibration and accuracy over time, making it suitable for both hobbyists and professionals who demand repeatable results. What you get A hole-positioning ruler system featuring T-shaped rulers, sliding ruler, engraved scale, calibration tool, locking mechanism, and high-precision spirit level — all CNC machined from anodized aluminum for durable, accurate performance.
