Tools and Hardware Reviews of Starrett 505A-12 ProSite 12-Inch Dial Protractor
Customer Review: Great tool!
Summary: 5 Stars
I read several old reviews here of the 505A-12 - and its smaller 7" sibling - and became nervous about the suggested lack of accuracy due to poor decal placement. So I contacted Starrett to verify if - as their web site claimed - the scales are now laser engraved and don't still employ simple decals. They assured me that the laser engraving was an enhancement implemented a few years back, and expressed frustration that Amazon reviews never expire due to age and this has lead to much confusion about their products.
Based upon this information, I bought a 505A from Amazon. It is, indeed, a great tool with a highly-accurate scale that exhibits none of the inaccuracies that others mentioned here years ago. One of the qualities that I like most - in addition to the accuracy, of course - is the very smooth yet snug action of the pivot, i.e. the pivot action is tight enough that the protractor will easily hold its position. You can use it in tight places where you can't read the scale until the protractor is removed from the measurement location; it's not going to move.
Wish I'd had this gizmo 40 years ago!
Description of Starrett 505A-12 ProSite 12-Inch Dial Protractor
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!

Measuring accurate angles and making accurate cuts saves you time, reduces the amount of material that you waste, and helps you get jobs done quickly and efficiently. That's where precision tools like the ProSite Miter Saw Protractor come in.
Featuring a patented, easy-to-use design, this tool offers two scales for quick reference. The scales have been laser engraved for exceptional accuracy with each measurement. The miter cut arrow shows the required angle for crafting a precise miter joint, while the single cut arrow provides you with the angle needed to fit a single work piece to an existing angle. The protractor gives you correct measurements every time, even when you're viewing your work piece backwards or upside down.
As durable as it is convenient, this protractor features machined aluminum legs and an adjustable friction pivot. Starrett also makes the smaller 505A-7, a convenient seven-inch protractor featuring the same easy-to-read dial and dependable construction, and the CP505A-12, a combination protractor that features a conversion table for use with compound miter saws plus a reference guide for working with common roof pitches.
