Editorial Review
No miter saw is complete without this patented and multiple award winning invention. This is the original and very popular 12-inch model of the Starrett ProSite Miter Saw Protractor. It is now also available in the conveniently smaller-sized 7-inch model, the 505A-7.
The Starrett ProSite Miter Saw Protractor takes error-prone calculations out of the process of miter cuts and other angle cuts. Simply set your saw to the angle that you read on the tool. There are absolutely no calculations. Upside down or backwards, the reading is always correct. These easy-to-use tools have two scales. The red scale and red "Miter Cut" arrow provide the exact miter saw setting for a perfect miter joint, while the black scale and black "Single Cut" arrow provide the exact miter saw setting for fitting a single workpiece to any angle.
The ProSite Miter Saw Protractors save time and reduce waste. They are ideal for carpenters, plumbers, and all building trades which require the measuring and transferring of angles. They are also invaluable for home use and do-it-yourselfers. They are the perfect and essential companion for every miter saw user. Buy both models and cover all your angles!

Piece of Junk 
2007-10-24
The scale was off by almost two degrees. I contacted Starrett and thoroughly discussed the problem with them. I sent the Protractor to them and they sent another one to me which was not correct either. I called Starrett again but couldn't get a guarantee that if I sent the second Protractor to them that I would receive one which was correct. The scales are a self sticking plastic that cannot be correct if they are off center when put on. This is another nice idea that hasn't been thoroughly thought out for production.
Good and Accurate

Mine is calibrated correctly, just enough pivot tension. Yeah, it's big and long, but to get a more accurate angle, 12 inches is appropriate and the heavy construction means damage is minimal, unless used as a pry bar. Don't let the previous whiners and prima donna psuedo craftsmen spoil this tool. On a large baseboard job alone, it's worth the time savings. Inside corners can be rectified by a caulk artist, but outside corners are critical. I no longer waste trim, time or guess...

I've used my new Starrett Protractor to set up my table and cross cut saws as well as find that difficult angle for crown molding.
Starrett Quality Takes a Nosedive with this Product 2007-09-02
50 years ago, my father, a watchmaker, told me that anything you own made by Starrett will be the best you can buy. I have a number of their products and have always agreed with Dad's assessment. Starrett lost it with this protractor. The accuracy is just not there. If you are doing rough carpentry work and need approximations, go for it, but if you are planning to use this protractor to set up anything in a quality home workshop, you better keep looking.
Disappointed!!
Great protractor at a great price! 2007-07-09
I read many of the product reviews for this protractor before I purchased one. This is a great protractor! If you have a need to cut any angle, then you need this handy tool. I have been teaching Agriculture Education for over 20 years ,and instruct kids in a woodworking and welding shop setting. I wish I had purchased one years earlier. This would make a great addition to any professional or hobby woodworker.

12" protractor

I have in the past needed a protractor with these features that enable me to use my miter saw more effitiently. I am looking forward to using the protractor in the short future.

I was extremely pleased with the quality of the product. Not only was it much larger than I expected, but it was made of metal, not plastic as I had assumed.

For the price of this item, I expected that the numbers on the dial should have alinged more precisely.
Excellent 2008-01-02
This angle finder works great, it has a tight feel so the angle can be measured and the angle finder moved to the saw without losing the measurement.
