RED TAIL Ruler Set: Three Precision Rulers That Mark True Every Time
Ever swapped rulers mid-layout only to find the scale you need is short, or your pencil drifted and threw the line off? Grabbing the wrong length or fighting a ruler that will not hold your mark slows you down and lets small errors creep into work you care about. The RED TAIL Ruler Set puts a stop to that. You get three rulers in 100mm, 150mm and 300mm, each built with the Tru-Mark Edge for accurate line placement every time.
Even better, each one slots straight into your Swan tool squares, so you can tailor your kit to the job at hand.
Key Features
- Three handy sizes: A 100mm, 150mm and 300mm ruler cover close-up detail work and longer layouts, so you always have the right scale within reach.
- Interchangeable with Swan tools: Each ruler swaps into the RED TAIL Offset Ruler, MERLIN Square and RIDGWAY Square, letting you customise your squares to suit your specific needs.
- Tru-Mark Edge: This proprietary edge places your line with no offset and no guesswork, so you mark accurately without centre-finding tricks or workarounds.
- Dedicated pencil saddle: Holds your pencil steady for consistent line placement, turning each ruler into a reliable marking companion on any precision task.
Ideal For
- Cabinetmakers and joiners chasing accurate, repeatable layout.
- Woodworkers who already own Swan squares and want to expand their kit.
- Detail work and longer marking jobs that call for different scales.
- Anyone who wants clean, consistent line placement in one set.

A quick tip: match the ruler length to your task before you start, reaching for the 100mm on tight detail work and the 300mm when you need to span a longer layout. Fit your pencil into the saddle and let the Tru-Mark Edge place each line exactly where you want it, then keep the set in its EVA tray so the anodised edges stay sharp and true between jobs.
