Starrett CP505E-12 Aluminum Electronic Combination Protractor, 12"

This protractor is the ultimate miter saw accessory. In ordinary use, it is a very accurate tool for measuring angles. You can use it to measure angles to transfer to your saw, or just use it to set your saw to precise angles.

The CP505E-12 really shines when installing crown molding. Just set (or measure) the spring angle of your crown moulding, then measure the angle of the corner. With this information and a few touches of a button, the CP505E-12 will tell you the bevel and AND miter angle for your compound miter saw.
