No-Hassle Triangles Gauge Create perfect triangles with no-hassle using these gauges. Effortlessly cut, mark, and stitch 1/-square or 1/4-square triangles without ever cutting a triangle, or guessing at the sizes. Use No-Hassle Triangles Gauge to make five block sizes for both 1/2- 1/4-square triangles: 2-1/2" (64mm), 3-1/2" (89 mm), 4-1/2" (114 mm), 5-1/2", (140 mm), and 6-1/2" (165 mm). Reference left side of gauge for 1/2-square triangles and right side for 1/4-square triangles. Sliding gauge locks for accuracy. CL9579
