UStar Adjustable T-shaped Ruler

We present an adjustable t-shaped ruler that will allow you to create perfectly perpendicular and parallel lines in pieces of wood, styrene, brass, and more. The shortest side can be adjusted in height, so you can place the ruler on or beside your cutting mat. Both the short and the long sides of the ruler are adjustable in length. Perfect for marking with a pencil or pen or as a straight guide for a cutting or engraving tool. The kit includes the ruler and the hexagonal screwdriver needed to tighten or loosen the screws.
