Interchangeable Precision Ruler System

The RED TAIL Ruler Set includes three interchangeable rulers in 102mm, 152mm, and 305mm lengths, compatible with other Swan measuring tools including the RED TAIL Offset Ruler, MERLIN Flat Double Square, and RIDGWAY Adjustable Carpenter Square.

Flexible Configuration for Layout Tasks

Whether setting up for fine joinery or general workshop marking, the set provides flexibility while maintaining consistent reference and line placement.

Tru-Mark Accuracy with Consistent Line Placement

Each ruler features Tru-Mark precision marking technology for true line placement and a dedicated pencil saddle notch for consistent, accurate marking, supporting repeatable results across multiple layout operations.

Durable Construction for Long-Term Workshop Use

Manufactured from high-quality anodised aluminium, the RED TAIL rulers are built for durability, stability, and long-term accuracy in daily workshop use.
