  • Aluminum and correct angle markings.
Style: 7 Inch
Very well made aluminum tool. Markings are clear and the angles are sharp. Can't go wrong with this well made tool and the price is just an added bonus. By one and compare it to an more expensive speed square and you will see what I'm talking about.
