Alvin LX710K 10-Inch Adjustable Triangle With Trig Scale - Clear Acrylic Drafting Tool

For drafters, architects, students, or anyone who needs to plot precise angles, the Alvin LX710K adjustable triangle is a classic tool. It's a 10-inch long, clear acrylic triangle that you can actually adjust to any angle you need. Just loosen the thumbscrews, set your desired angle using the built-in rise/slope graduations and degree scale, and tighten it back down – it locks securely in place. The clear body lets you see your work underneath, and it has an inking edge for sharp lines. It's 0.12 inches thick, giving it a solid feel. Much more versatile than a fixed set of triangles. Whether you're doing technical drawings, classroom geometry, or DIY projects requiring accurate angles, this professional-grade tool from Alvin (a trusted brand for over 50 years) is a great investment. Comes with instructions to get you started.
