The body is machined using CNC (Computer Numerical Control) technology, delivering precise edges for accurate angle marking, stair layout, and roof rafter cuts. A low-glare powder-coated finish reduces eye strain in bright conditions. Permanent graduations and numbers are laser-etched for long-term readability even after heavy use. The thick edge doubles as a saw guide, making it a practical single-tool solution for carpenters, framers, and general contractors who need consistent results on repetitive cuts.\u003c\/p\u003e\u003cp\u003eThe RAS-1B is suited for residential and light commercial framing applications. The 7-inch size is the standard choice for marking and cutting dimensional lumber. Continuous scribing notches at 1\/8-inch intervals allow fast rip lines, with dedicated notch positions optimized for common rip widths of 3.5 inches and 5.5 inches. This square is a standard carry for framers, finish carpenters, and roofing crews working with 2x4 and 2x6 stock.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid 7-inch aluminum body resists flex and corrosion\u003c\/li\u003e\n\u003cli\u003eCNC-machined edges for precise, repeatable angle transfers\u003c\/li\u003e\n\u003cli\u003eThick edge functions as a direct saw guide\u003c\/li\u003e\n\u003cli\u003e1\/8-inch continuous scribing notches for fast rip layout\u003c\/li\u003e\n\u003cli\u003eOptimized notch positions at 3.5 inches and 5.5 inches for dimensional lumber\u003c\/li\u003e\n\u003cli\u003eLow-glare powder-coated finish for comfortable use in bright light\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 7-inch rafter square for use with dimensional lumber in residential and commercial framing, roofing, and finish carpentry applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eNo power tools or fasteners are required for use.
