Q: Does the edge fence adjust or is it fixed?
A: The 3D fence structure is built into the ruler to sit securely against the edge of a board. It provides a stable, consistent reference point for drawing precise, repeatable layout lines without slipping.
Q: What sizes are available and which should I choose?
A: Three sizes are available — Small (11×7 cm), Medium (16×11 cm), and Large (20×13 cm). Choose the small for detail work and tight spaces, the medium for everyday cabinet and trim tasks, and the large for wider boards and panel layout.
