Features:

• 7-inch miter saw protractor with two scales--red "miter cut" scale and black "single cut" scale
• Allows direct transfer of the work angle to the miter saw in 3 steps with no calculations
• Durable 1/4-inch thick aluminum alloy; Teflon O-ring for smooth, precise operation
• 12-inch version also available to cover

Editorial Review:

Takes error-prone calculations out of the process of miter cuts to ensure perfect miter joints every time! Simply set your miter saw to the angle that you read. Upside down or backwards, the reading is always correct. Features two scales: red scale and arrow show the angle for a miter joint, while the black arrow and scale provide the angle to fit a single workpiece to an angle. Durable aluminum with Teflon O-ring for smooth and positive operation. Patented.

Mine isn't accurate:

Considering it is used to gain precision cuts, it would be nice if it was accurate. Mine off by a degree or so. If I put it at 0 degrees on the single cut(which is really 90 degrees) the miter cut should be at 45 degrees, and it isn't. More like 44 degrees. There is no way to adjust the stickers/plates that mark these angles. Not a major deal, but I bought it to gain as much accuracy as possible, so that doesn't help. That being said, this really is a must have tool for a miter saw. I would recommend... more info

Starrett Prosite Protractor 505A-7:

This tool is devilishly simple and accurate. It will cut time and wasted material when you measure and cut molding. The tool gets the precise angle and tells you how to set the miter saw. Perfect angles the first time! No more "trial cuts" that have to be tweeked to fit. The 7" model fits in the toolbox and is worth the cost. The 12" may not fit in tight corners but is identical to the 7" protractor. It is solidly constructed from aluminum and will last a long time in a tough construction environment.

Starrett Protractor:

This is something I've been looking for, a long time! What could be better than checking the angle, and then seeing the angle needed for the cut! Excellent buy !

Starrett ProSite Protractor 505A-7:

Overall, a very good product. Easy to use and easy to read scales. Would be better if one of the legs was offset so that both legs would sit flat to the surface during use rather than having to keep pressure on the one leg to keep tool from rocking over.
