The MatMaster Rule is extruded from high grade aluminium especially selected to reduce warpage and bowing. The design features a deep channel so that the FrameCo range of bevel cutters, straight cutters, grooving tools and glass cutter will all attach directly to the rule. The white and black metric/imperial scale is easy to read. A small lip on the scale edge prevents pencils or knives damaging the scale, and the “0” point of the scale is set back from the edge of the rule. The feature that makes the FrameCo Rule the best, is the two solid rubber feet running the full length of the rule to prevent it slipping, and it is twice the weight of other rules, giving better control.
