The MERLIN is a layout square that combines the functions of a double square, framing square, and ruler into one lightweight, flat-profile tool. Whether you're building face frames or laying out joinery, the Merlin Square stays flat, accurate, and right where you need it.
- Lay Flat Design - The only square on the market that lays completely flat in any position. Ideal for inside and outside layouts, edge referencing, and ruler-style measurements.
- Built-in Shelf Tab - This feature adds stability and control during layout, making it easier to maintain consistent reference points across materials.
- Expandable Platform - The ruler is interchangeable with the RED TAIL Ruler Set (SWAN-R4612AL) so it can be customized to meet your needs.
- Tru-Mark Edge - This proprietary feature (standard on Swan Tool Group's RED TAIL Rulers) ensures accurate line placement every time, eliminating the need for center-finding tricks or secondary tools.
