CNC milled from a solid 4mm plate of high-quality T6 Aluminium, this square features fully deep-engraved scales that guarantee permanent readability. With an unmatched right-angle precision of +\/- 0.008° along its entire length, the G-Rafter 180 PRO delivers absolute accuracy for flawless timber layout on any demanding New Zealand job site.\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: Permanent Precision\u003c\/b\u003e\u003c\/p\u003e\n\u003cp data-path-to-node=\"13\"\u003eIn professional framing and roofing, measurement drift caused by faded markings leads directly to compounding errors and costly material rework. Cheap squares force you to guess your angles after a few months of heavy use. The TrigJig G-Rafter PRO solves this through enhanced anti-wear engineering, ensuring your hip, valley, and protractor markings never rub off. Furthermore, the integration of a high-visibility 360° bubble vial in the dual-sided fence means you can instantly check level and plumb without walking back to your tool belt to switch tools. This combination of permanent accuracy and operational speed makes this square a strict buy-once, cry-once investment.\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 G-Rafter 180 PRO:\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\"\u003ePermanent Markings:\u003c\/b\u003e CNC deep-engraved scales provide permanent visibility, immune to job site abrasion.\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 High-visibility 360° bubble vial allows for instant plumb and level checks.\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\"\u003eAbsolute Accuracy:\u003c\/b\u003e Milled in Great Britain to an extreme tolerance of +\/- 0.008°.\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\"\u003eAdvanced Scribing:\u003c\/b\u003e Features scribe notches every 5mm and 1\/3rd scribe marks specifically for common timber widths.\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 Equipped with a metric rafter length per metre run table and a dedicated birdsmouth line for complex cuts.\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\"\u003eMaterial\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"17,1,1,0\"\u003e4mm thick T6 Aluminium Plate\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"17,2,0,0\"\u003e\u003cb data-index-in-node=\"0\" data-path-to-node=\"17,2,0,0\"\u003eManufacturing Origin\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"17,2,1,0\"\u003eMade in Great Britain\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\"\u003eMarking Technology\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan data-path-to-node=\"17,4,1,0\"\u003eCNC Deep Engraved \u0026amp;
