The Square 30/40/50mm is a pocket product that uses the classic Pythagorean 3/4/5 triangle. Handy for quick right-angle checks. Due to the 3/4/5 triangle not having round numbers for either angle except the 90-degree corner these have not been included on the product.
Part of the Technical Collection for those seeking greater precision in their work. The tinted transparent grey acrylic allows you to see the working area. The markings are etched into the rear face making them easily legible whilst ensuring they can never be worn away over time. Made in the UK from Italian made 100% recycled and recyclable acrylic.
