What it is
Ratioparts Alu-Cut line in 2.7 mm (0.105 in), with a hexagonal, six-point profile, sold as a 15 m blister pack in orange (part 006,323). This page’s address says “square”; the product we link to is hexagonal. The listing showed no price when we checked in October 2026.
Why an edged profile?
Edged lines — square, star or hexagonal — slice grass and weed stems rather than tearing them, leaving a cleaner cut and moving through coarse growth with less drag. Six edges give a smoother cut than four. The trade-off is faster wear against paths, kerbs and walls, where round line lasts longer.
Will it fit?
2.7 mm suits mid-size petrol trimmers and brush cutters whose heads accept that diameter (for example the Husqvarna T35, rated 2.4–2.7 mm). It’s too heavy for small electric and most battery trimmers. Our line size guide explains how to check.
Bigger packs
15 m is a refill or two. If you trim regularly, a long spool is much cheaper per metre — compare options such as Oregon Duoline 2.7 mm × 140 m in the best brush cutter line.
