The RED TAIL Offset Ruler 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 ( standard on our RED TAIL Rulers) 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 RED TAIL Offset Ruler into a reliable marking companion for any precision task.
• Expandable Platform – The ruler is interchangeable with the RED TAIL Ruler Set (Pt# R4612AL) so it can be customized to meet your needs.
