ProSite Miter Protractor, 7" Narrow Plastic | With Two Laser Engraved Scales, Ideal for Carpenters, Plumbers, and DIY Home Improvement, 505P-7

This Starrett miter protractor is one of those tools that quickly becomes indispensable if you do finish carpentry, trim work, flooring, or woodworking. Instead of trying to guess or manually calculate angles, you simply match the protractor to the corner and it gives you the exact angle needed for your miter saw. It saves a lot of time and helps eliminate costly mistakes. The laser-engraved markings are easy to read, and the tool feels solid and well-made. The pivot stays tight while still moving smoothly, allowing you to transfer measurements accurately without the angle shifting. It's especially useful for inside and outside corners that aren't a perfect 90 degrees. As expected from Starrett, the quality is excellent and built to last. Whether you're a professional contractor or a DIYer tackling home projects, this tool makes achieving precise miter cuts much easier and far less frustrating.

This is an excellent tool, especially for someone with no previous experience cutting crown molding. Step-by-step instructions are included, showing what bevel angle and miter angle to use on a compound miter saw after the measurement from the tool is known. The scale is easy to read, and the plastic body is sturdy but light weight. The tool can be used for a wide variety of measurements beyond crown molding. A few dollars invested in this tool could save a lot of trial-and-error aggravation, not to mention wasted material. Highly recommended!

There are likely quite a few fakes in circulation from Amazon and elsewhere. I ordered one from a third-party seller with fulfillment by Amazon, but upon close inspection after receiving the item, it turned out to be a fake. I purchased a second that was actually "sold by" - not just "fulfilled by" - Amazon and from inspection I'm sure it is genuine. Please see my photos with the details. The fake was very close in almost every way. Without a real one next to it, it was a challenge to identify. If I had bought it as an off-brand out of a bargain bin, I probably wouldn't have had any complaints. It still looked pretty functional. I wanted the real tool for this though; I just couldn't get past the concern that I would end up with less precise finished miters and/or more rework with the fake. The fake I got appeared to be pretty close on accuracy though. Differences: Laser Engraving- Real has true laser-etched dial with consistent alignment of markings and numbers. The laser actually "digs" tiny trenches with a little roughness at the edges of each engraved "trench". Feels a little like sandpaper when sliding finger across markings. Fake had some sort of printed markings deposited on top of the surface with some of the digits poorly aligned. Markings could be felt, but were much smoother than laser engraved. Would expect less precision in this method of manufacture. Fit & Finish- Real has a bold yellow inlay with a precise geometry that lays in flush as intended. Fake had a little more drab, somewhat translucent, yellow inlay with less precise geometry that didn't entirely lay in flush as intended. Could just barely see some the structural ribs in the plastic behind the yellow inlay on the fake because of the inlays translucency. Pivot Screw- Real has a pivot screw head that is ø0.65" (21/32") [16.5mm] in diameter. Fake had a pivot screw head that was smaller at ø0.60" (19/32") [15.2mm]. Package- Real had a Proposition 65 warning sticker on the back and was not stapled closed. Fake was stapled closed and did not have a Proposition 65 warning sticker. Printing on fake was extremely close to that of the real article. Fake happened to have some barcode stickers on the exterior, but still had the same original barcode inside the package. Some of the details may be different on other fakes. These are just the most discernible discrepancies I noted on this specific fake. My rating is based entirely on the legitimate product I received, not on the fake.

Firstly, keep in mind, I purchased this for which it wasn't necessarily designed. I'm a coach in First Lego League; where kids builds robots and program them to complete a set of tasks. I needed to have an easy way for them to calculate degrees. We started off buying have it complete straight and then setting the angle. Well, the numbers we were reading didn't work right. It took sometime to understand how to explain this to a group of 10 year olds. We finally worked it out right, but it ended up being to cumbersome/confusing for what we were using it for. Something didn't seem logical to me, but then again I'm not a contractor. I'm a programmer. You may notice that the units starts to squeak after a while. Just tighten the screw under with your thumbnail and you'll be good to go. Overall, the unit feels nicely built and accurate enough. It's just that one ring of numbers is a bit confusing but also remember we were using it for something completely different. I'd probably find it a lifesaver if I was using for miter cuts, but then again, I'm fine with a standard angle gauge.

2nd one I’ve purchased.

This is such a great tool!! It has made putting in baseboards a breeze. My home has a bunch of unusual angles, and as an older home, many of the walls aren’t even plumb. Using this, I can get each miter cut done perfectly. Add in some CA glue and activator to fix the boards ahead of time, and it’s a cinch to have perfect angles. I can’t imagine trying to line everything up without this.

This is about as accurate as most miter saws found on job sites. I've been doing custom cabinetry and scenery/general construction for over 20 years... and I bit the bullet in 2012--4 years ago now? I used to obsess about getting the perfect, closed angle for years, but this is much faster. Sure, you can tweak and really fine-tune your cuts, in order to keep grain continuity, etc, but for general molding where accuracy within 1/2 degree is close enough (you can always cut long and trim-to-fit if needed) it's a huge time saver. You get actual numbers you can use on miter or table saws. It's a lightweight tool--I was hesitant to buy a piece of plastic, but considering I'm often carrying tools to job sites via bicycle and backpack--I appreciate the lack of weight! I highly recommend this angle finder--it's held up for four years now--pretty sure it'll hold up for four more. For those who read reviews saying it's hard to figure it out--the "single cut" is literally where you draw the line and cut for the one angle. The "miter cut" is the bisected angle (half of the "single cut").

I've used this protractor several times so far. I'm new to Woodworking, but gaining more skill and knowledge daily. I've invested in quite a few measuring tools, so I can make sure I have accurate guidance when it comes to cutting :) Reading the dial originally was a bit tricky. Once you learn how to read it, its quite an accurate tool A few positives: ** Great size. Works well with my dewalt 12" dual bevel miter saw ** Rotates quite easy and its incredibly easy to read! ** If you plan to cut any sort of trim ~ GET THIS PROTRACTOR! I wish all my tools were built this well ... Plan to look at other Starrett measuring tools in the future since I like this protractor so much.

Ich habe damit Stuckleisten ausgemessen und später zugeschnitten. Tolle Ergebnisse!

Very handy little gadget. Great for setting up compound mitre saw.

Buen precio y versátil, no obstante, no es fácil precisar el ángulo a primera vista, todo aquellos por encima de 90º, tendréis que sumar 90 + lo que resulte señalado con la flecha central. Al segundo ángulo que se mida, se le coge el tranquillo..

Attrezzo semplice di buona fattura che semplifica notevolmente il lavoro.

Tres bien
