The Creative Grids Half Rectangle Trim Tool is a specialty acrylic cutting tool designed to simplify the construction and trimming of half-rectangle triangle (HRT) units. Unlike half-square triangles, HRTs have unequal side lengths and require precise trimming for accurate piecing. This ruler allows quilters to trim HRT units in multiple sizes and orientations—both left and right—using built-in ¼" seam allowance guides and alignment markings.

Perfect for modern layouts, diamond blocks, and angular piecing, this tool features Creative Grids’ exclusive non-slip grip and high-contrast black and white markings for visibility on both light and dark fabrics.
