CNC milled from a single, solid piece of 4mm T6 aluminum plate in the UK, this metric rafter square delivers an extreme right-angle precision of +\/- 0.008° along its entire length. Unlike mass-produced cast squares, the Grafter 180 integrates a highly sensitive 360° bubble vial directly into the dual-sided anodized fence, allowing tradesmen to find level and plumb marks instantly without reaching for secondary tools.\u003c\/p\u003e\n\u003cp data-path-to-node=\"13\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"13\"\u003eThe Pro's Equation: Precision Without Compromise\u003c\/b\u003e\u003c\/p\u003e\n\u003cp data-path-to-node=\"13\"\u003eIn structural framing and high-end roofing, measurement slop dictates the difference between a seamless fit and costly timber waste. Cheap, stamped squares introduce micro-errors that compound over large spans. The Grafter 180 eliminates this margin of error completely. Featuring stepped stud-off notches for precise pencil marking and highly abrasion-resistant laser-etched scales, it ensures every mark is fast, repeatable, and deadly accurate. By investing in this British-engineered precision instrument, professionals drastically reduce layout downtime and prevent expensive rework, making it a critical, tax-deductible asset for high-performance crews.\u003c\/p\u003e\n\u003cp data-path-to-node=\"14\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"14\"\u003eWhy Pros Choose the TrigJig Grafter 180:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul data-path-to-node=\"15\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"15,0,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"15,0,0\"\u003eUnmatched Accuracy:\u003c\/b\u003e CNC-milled construction guarantees a strict +\/- 0.008° right-angle precision.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"15,1,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"15,1,0\"\u003eIntegrated Spirit Level:\u003c\/b\u003e A built-in 360° bubble vial allows for instant plumb and level checks during layout.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"15,2,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"15,2,0\"\u003eExtreme Durability:\u003c\/b\u003e Bright white, laser-etched markings offer extreme abrasion resistance against daily job site wear.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"15,3,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"15,3,0\"\u003eSmarter Scribing:\u003c\/b\u003e Features stepped stud-off notches and 5mm scribe notches to account for marking medium thickness.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"15,4,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"15,4,0\"\u003eRoofing Ready:\u003c\/b\u003e Includes a comprehensive rafter length per metre of run table and a dedicated birdsmouth line.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-path-to-node=\"16\"\u003e\u003cbr\u003e\u003c\/h3\u003e\n\u003ctable data-path-to-node=\"17\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFeature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eDetail\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"17,1,0,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"17,1,0,0\"\u003eModel\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"17,1,1,0\"\u003eGrafter 180 Rafter Square\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"17,2,0,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"17,2,0,0\"\u003eMaterial Construction\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"17,2,1,0\"\u003eCNC-Milled 4mm T6 Aluminium Plate\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"17,3,0,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"17,3,0,0\"\u003ePrecision Tolerance\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"17,3,1,0\"\u003e+\/- 0.008° along the entire length\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"17,4,0,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"17,4,0,0\"\u003eMain Rule length\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"17,4,1,0\"\u003e182mm (Metric layout)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"17,5,0,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"17,5,0,0\"\u003eLevel Integration\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"17,5,1,0\"\u003eBuilt-in 360° bubble vial inside the fence\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"17,6,0,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"17,6,0,0\"\u003eHardware Components\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"17,6,1,0\"\u003eStainless steel machine head bolts\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"17,7,0,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"17,7,0,0\"\u003eSurface \u0026amp;
