The Red Tail is a precision offset ruler designed to simplify layout tasks for paneling, custom cabinetry, and other woodworking projects. Its flat-edge slider combines four essential tools into one: an offset guide, 90° square, 45° square, and standard ruler, ensuring accurate markings and efficient workflow for craftsmen.

• Built-in 90° and 45° layout guides make repeatable angle marking effortless. Ideal for trim, casement moldings, and box making.
• Lay Flat Design - for added versatility and easy layout work.
• Tru-Mark Edge - This proprietary feature ensures accurate line placement every time, eliminating the need for center-finding tricks or secondary tools.
• A Dedicated Pencil Saddle ensures consistent line placement, turning the OR800 into a reliable marking companion for any precision task.
• Expandable Platform - The ruler is interchangeable with the Red Tail Ruler Set (R4612AL) so it can be customized to meet your needs.
