Compact Multi-Function Offset Layout Tool

The RED TAIL Offset Ruler is a compact, multi-purpose layout tool designed for accurate marking, measuring, and edge referencing in woodworking and joinery applications. Combining the functions of an offset parallel guide, 90° square, 45° square, and standard 203mm ruler, it streamlines layout work while maintaining a flat, stable profile.

Integrated Angle Guides for Repeatable Marking

Integrated 90° and 45° layout guides make repeatable angle marking quick and reliable, particularly when working on trim, casement mouldings, box making, panelling, and custom cabinetry. The offset guide allows consistent marking from edges, improving accuracy across repeated measurements.

Tru-Mark Edge for Precise Line Placement

The Tru-Mark Edge places the marking line exactly where intended, eliminating offset errors and reducing the need for workarounds or visual compensation. A dedicated pencil saddle notch supports clean, consistent line placement, making the RED TAIL Offset Ruler a dependable companion for precision layout tasks.

Lay-Flat Stability with Durable Construction

Its lay-flat design ensures stable contact with the workpiece, whether used as a ruler or an angle guide. Manufactured from high-quality anodised aluminium, the RED TAIL Offset Ruler is built for durability, long-term accuracy, and everyday workshop use.

Expandable Platform for Ongoing Versatility

The expandable platform allows the ruler to be changed to fit 102mm, 152mm and 305mm Red Tail Rules to suit individual preferences, ensuring flexibility as layout requirements evolve.
