## Description

Starrett ProSite Miter Protractor, 7" Narrow Aluminum | With Two Laser Engraved Scales, Ideal for Carpenters, Plumbers, and DIY Home Improvement, 505A-7 - Construction Protractors - desertcart.com

Review: A carpenters best friend. - Amazing little job site tool. I use it all the time. It finds the perfect angle every time. I highly recommend this tool. Makes the job so much easier.
Review: 5 star quality, 4 star price. - Look, let's be blunt. No matter how good your hotshot framing and drywall crews are, even new construction is never square. And in old houses, it just gets worse. And this doesn't even take into account irregular angled walls that are anyone's guess. Now I know the rest of you all payed attention in 8th grade geometry, but for those of us who don't like mulling over math problems on the job site, the Sarrette is as good as it gets. Read the single cut angle off one side. Read the miter cut off the other. And the tool can (and should) be used to set your miter saw to the exact angle you need. Read it off the wall, set the blade using the tool, cut. Perfect. Oh, the pain I could have saved myself if only I'd bought one of these earlier. Cutting scrap test pieces and banging my head against the wall wondering how I'd gotten it wrong again. Basically, if you do a lot of finish carpentry, having one of these will save you a lot of time and money. Even for the homeowner that's doing a few rooms, it's probably worth it if you want really good joints, especially in an old house where most of your "90 degree" corners will be off by several degrees from 90. I only have two minor beefs. OK, for me it's worth it as I'll easily save it back over and over again. In fact I bought two. But c'mon guys, $42.99? I'm surprised someone hasn't ripped off the idea and isn't making one at $14.99, but keep charging this price and someone soon will. Also, I'd like an easy way to adjust the tension of the legs so it would hold the exact angle more firmly. One of my miter saws has a habit of swinging slightly when you reach to tighten the adjustment knob. Then the blade hits the protractor and messes up the reading. The ease of use does make up for the shortcomings. If you have a miter saw and do finish work, you need one of these.

## Questions & Answers

**Q: How good is this tool for bevel cuts ?**
A: I have never personally had to make a bevel cut but this tool could measure any type of angle.  If you do woodworking, this tool will definitely come in handy for crown molding and other situations where you have to figure out an angle to get a tight precision fit.  I am glad I own this tool as it has helped me many times.

**Q: Is this laser etched now or still has the sticker? Accuracy problem with sticker fixed now?**
A: I just received one purchased in 11/2014 and although it says "laser etched" it looks more like a sticker to me.  In any event, mine has the 'mismatched scales' problem others have reported. The package did not appear to have been opened before I received it but it may well have been, or perhaps someone received it before I did and checked right through the packaging before opening it to observe the issue. Mine is off about 1/2 degree which doesn't sound like much but it actually makes a difference on larger moldings and casings. I am contacting Starrett for help - I think that's better than just doing a replacement with the seller since if everyone starts doing this we will pass the bad ones around for years.

**Q: Starrett company representative, please confirm: "New upgraded design includes LASER ENGRAVED DIAL for EXCEPTIONAL ACCURACY"**
A: There now seem to be at least two different-looking versions of this tool with the same model number available online (both Amazon and elsewhere) and ranging in price from $50 to over $100. For example the video on the Amazon page does the demo with a different tool (about $50) than the one shown above for $100. Which version is the newest most "upgraded" version, and which ones have been sitting in a warehouse? For $100 and claimed to be "upgraded" and engraved, I expect an accurate one first try, no returns or return postage or delays - or I might as well just buy the plastic version.

**Q: I'm not empressed with Your cp#505a REVIEWS concerning it,s ACCERICY HAVE YOU MADE ANY IMPROVMENTS?**
A: I'm not sure what you're asking.  I bought this, found it defective, got a replacement, found it also defective, and gave up.  I haven't looked at another since.  Perhaps they are better now, I don't know.  I now use the old fashioned (that means good) Starrett Builders Tool No. 439-24.  It is excellent and lives up to the Starrett brand.  Hope that helps.

### ⭐⭐⭐⭐⭐ Must Have Protractor
*by K***R on January 16, 2012*

This is just a very nice tool, well made, hefty, comes with a carrying pouch for protection and it has that "old school" feel, not some flimsy cheapo tool. This protractor is a solid tool, accurate, and a pleasure to use. I use it for setting table saw fence and miter gauge alignment, and I check the lineup of my Festool MFT track, and any angle that needs stetting I always check for square and with this Starrett 4041-12 it is a snap. I keep it within reach and always verify my setups. There nothing better than knowing that you are dead on every time. I have other devices that serve the same function, even digital ones but tins is the one sitting right where I am working, always, and I trust it implicitly it does not let me make mistakes. I think one reason that I choose this is that it just feels right in your hands the movement is firm and smooth and you know you can trust it. Although the movement is quite firm and retains it's setting well, it can be prone to accidental movement as there is no physical lock so you need be careful if you are taking the measurement to another place, this is not a problem as it holds the setting as long as you don't somehow bump the protractor and move the setting. I don't even worry about that as there is nothing wrong with working carefully, in fact that is a plus you ought to be paying attention to the job at hand. I am most satisfied with this item and highly recommend it to anyone who wants to get serious when dong setups in the shop. Don't accept some crappy plastic substitute, ignore the price, pay the man and be happy knowing you will know the angles for years to come.
