22.5°/90° Rapid Positioning : Pre-set standard 22.5° bevel angle and perfect 90° right-angle reference edge eliminate the need for measurement and calculation. Achieve positioning in just one second, significantly improving the efficiency of material cutting and line drawing. 3D Spatial Measurement Expert : The three-dimensional structural design allows for easy measurement of an object's length, width, height, and spatial angles. It solves the challenges of measuring complex three-dimensional workpieces and eliminates the need for repeated flipping. Pegboard Matrix Positioning System : The ruler body is covered with a pattern of regular, precision holes (pegboard design), which facilitates quick positioning, marking, and securing of workpieces or assisting in drawing parallel and equally divided lines, achieving multi-functional rapid positioning. Aluminum Alloy Durability : Made from high-quality aerospace aluminum, it is lightweight yet strong and resilient. It is resistant to drops and bending, maintains its shape, and is wear-resistant. It withstands harsh workshop environments and has a long service life. Efficient Line Drawing Assistance : The straight edge, right angle, and beveled edge all serve as stable and reliable references for line drawing. Combined with the hole design, it makes it easy to draw parallel, perpendicular, and angled lines quickly and accurately., Manufacturer: LuLobtg
