【Multi-Function, High Precision】This aluminum height gauge offers a continuous 0–50 mm (0–2 in) range for fast, accurate setting of table-saw blade height, drill-press depth, planer cut depth and other critical machine parameters, boosting setup speed and repeatability. 【High-Strength Aluminum Alloy】CNC-machined from high-grade aluminum and hard-anodized for scratch and corrosion resistance. Etched graduations stay clear and accurate for life, eliminating reading drift. 【Efficient Batch Marking】Set the desired height and scribe perfectly aligned reference lines across multiple work-pieces—ideal for drawer sides, laminates or mortise-and-tenon batch work—without the errors of individual measuring. 【Easy Working】A smooth micro-adjust slide provides fine height control, while a reliable lock knob prevents drift. The lightweight, hollow-backed body reduces fatigue during extended use. 【Stable, Wide Base】The broad, flat base seats solidly on machine tables or tracks, preventing rocking or tilt and giving you a rock-solid reference plane every time., Manufacturer: LuLobtg
