Pacific Arc Drafting Triangle 18 in 45/90 Degrees - Precise Orange

In this review the Pacific Arc Drafting Triangle proves to be a straightforward, dependable tool for anyone who needs clean angles and a durable, visible template. Designed for architects, engineers, quilters and students, the biggest reason to buy is its combination of an accurate 18 in edge and a strong.080 in acrylic construction that resists warping while remaining easy to sight through thanks to its fluorescent orange finish. It performs the basic tasks of a drafting triangle without unnecessary features, making it a practical choice for regular use.

Key Features

• Accurate 18 in length: The non-graduated 18 in edge gives a reliable straight reference for long lines and edge alignment on large sheets or fabric.
• Distinct 45/90 and 30/60/90 corners: Multiple corner angles allow quick switching between common geometric needs without swapping tools.
• .080 in acrylic construction: The fairly thick acrylic resists bending and holds a straight edge for consistent line work over time.
• Fluorescent orange visibility: The bright color keeps the triangle easy to spot in a busy workspace and reduces the chance of losing it in a pile of supplies.
• Plain strong edge: The non-cutting, durable edge is designed for repeated use and works well with pencils, pens and rotary cutting against a flat surface.

Who It's For

The triangle is best suited to professionals and hobbyists who need a large, durable straightedge and common angle templates: architects laying out plans, engineers marking up drawings, quilters who want long, consistent guide edges, and students learning technical drawing. Its size and rigidity make it a good studio or classroom tool rather than a pocket accessory.

Those who need fine graduated measurements on the edge, a smaller portable option, or specialized transparent templates with printed grids should look elsewhere; this model is non-graduated and focuses on solid edges and angle accuracy rather than measurement marking.
