The bottom line: this is a simple, accurate tool built from clear.080 in acrylic that lets users mark precise angles and long straight edges without the flex or opacity problems of cheaper plastics.

Key Features

• Professional drafting accuracy: The 45/90 degree geometry provides consistent, repeatable angles useful for architectural and engineering drawings.
• Clear acrylic construction: Made from pure.080 in acrylic so lines beneath the triangle remain visible while the material resists warping during normal use.
• Strong plain edge: The solid, unscored edge stands up to repeated rulers and cutting tasks, making it suitable for drafting and fabric cutting.
• Long 20 in length: The full 20 in side gives a useful, uninterrupted straight edge for large-format work and quilt pattern layout.
• Versatile corners: The 30, 60 and 90 degree corners expand the tool's usefulness beyond a single angle to common drafting and quilting needs.
• Gift-ready utility: A practical present for design students or professionals who appreciate reliable, no-frills tools.
