The Alvin Tru-Angle Adjustable Triangle provides the functionality of a 45-degree by 90-degree triangle with additional features. It comes with a white protractor that allows extended angle adjustment from zero degree up to 90 degrees. These angles can be set from the baseline with ½-degree accuracy. With two rows of graduations, this protractor shows complementary angle at any setting.
This adjustable triangle is equipped with aluminum thumbscrew that securely locks the selected angle for quick pick up and easy manipulation. Made of 0.10-inch thick high-impact acrylic material that is optically clear, it has close pencil tolerance and eliminates parallax. This is to ensure accurate and perfect drawings.
The Alvin Tru-Angle Adjustable Triangle is marked with die-engraved graduations for high visibility. This is to guarantee exact and correct angle settings. To accommodate a wide variety of drawing and drafting applications, it comes in four different sizes.
