Sturdy tool: aluminum alloy frame with balanced weight distribution provides stable performance on all jobs. It functions as a mobile measuring tool that adapts to diverse work environments to deliver precise results on the go. Multiangle functionality: combines depth measurement and level control with variable angle settings for woodworking and construction projects. The design emphasizes practical, taskoriented features to optimize performance. Efficient working design: integrated guide rail and scalebased marking streamline workflows and produce precise cutting lines. Permanent markings: engraved scale is abrasion and faderesistant for clear visibility and longterm measurement accuracy. Use scenarios: Onsite framing and layout in carpentry where quick depth checks and reliable level references are needed. Cabinet installation and furniture finishing requiring accurate alignment, plumb, and level results with precise cut lines. Portable measurement in workshops or job sites when working across varied environments and angles.
