What it does Measures height using a clear scale mark on the back so you can check distances quickly and accurately. Doubles as a marking gauge: the tip is positioned at half the workpiece height and can be run horizontally to scribe a consistent mark. Why you need it Speeds layout and inspection by combining measurement and marking in one compact tool. Reduces hand fatigue and improves control thanks to a hollow back that lowers weight and enhances grip. Built from durable aluminum alloy for wear resistance and long service life, so it stands up to regular workshop use. Key features Back scale marking for straightforward height measurement. Hollow back design to reduce weight and improve handling. Sturdy aluminum alloy construction for corrosion resistance and toughness. Tip configured for horizontal marking at the workpiece midpoint. Typical applications Woodworking: mark consistent layout lines for dadoes, shelves, and trim installations. Metalworking and fabrication: check part height and scribe reference lines before cutting or welding. Home DIY and repairs: align fixtures, mark drill locations, and transfer measured heights between parts. Practical benefits Combines two common tasks (measuring and marking) to save time and reduce tool changes. Lightweight, easy to hold and carry between tasks. Durable material minimizes the need for frequent replacement. Compatible with general workshop, fabrication, and DIY tasks where quick height checks and consistent horizontal marking are required.
