The Model #505P-7 Miter Saw Protractor is an invaluable tool for carpenters, plumbers, building trades, home use, and do-it-yourselfers. This construction protractor is the best in its class for build quality, overall satisfaction, value for money, and accuracy. It features two laser engraved scales that make it convenient for various measurements and two easy-to-read scales that allow you to directly read from the work to the miter saw. Additionally, it comes with an O ring that ensures a smooth and precise operation.Becca: I am no DIY expert and never thought I would be able to cut weird angles for molding, but this tool made it possible. Easy to use, a bit if trial and error, but does the job.

Bob: Just did a lot of trim work and figured I would get one of these to make better cuts. Super easy to use and really gave me tight fitting cuts. Should have bought one of these years ago.

BlueBirdPaintingVaBlueBirdPaintingVa: Its accurate. Ive used it on a small trim job and the miters were tight. Eliminates ugly caulk and speeds things up. The quality is ok. If you put some twisting motion on it, it will flex some but its not flimsy. Has a adjustment nut on the back for calibration if needed which is nice. The printed ink on the gauge doesn't appear to be jet black, its a lighter shade of black. It is just printed, the marks are not embossed or imprinted into the plastic. I do not store it in my toolbox where it will get beat around or anywhere it will get scratched up. Comes with a felt pouch. I keep it in that and in my drivers door pocket with the electronics gadgets like laser measurer, stud finder and etc. All in all it was a good purchase and I see no reason for paying more for the yellow one.

S. Griffin: The need for this item and others like it arises out of the longstanding tradition of calibrating tools with the reference point being a square cut, so a square cut is labeled as zero on a miter saw, and angles other than square are measured by their degree of deviation from zero (square.) It's a perfectly reasonable way to introduce simplicity to the mitering process, but a square cut, in strictly geometric terms, is actually 90 degrees. Labeling it as zero works well because on a miter saw where 90 degrees is defined as zero, a 10 degree cut (for example) on the left is the same as a 10 degree cut on the right without requiring addition or subtraction from 90 to make equal left and right cuts, whereas if a square cut were labeled as 90 you would have to set the saw on 80 degrees on the left and 100 degrees on the right to make the same cut. The problem with labeling 90 as zero comes when you measure a non-standard angle on a wall or staircase or whatever, and wish to transfer that angle to the appropriate cut on a miter saw; from the geometry of it, you would ordinarily just measure the angle in degrees and divide by 2 to bisect the angle, but when you take that angle to the...

bridan: Looks the same and performs just as well as the more expensive versions.

yannick: Donne une idée de l'angle requis mais ce n'est pas l'outil idéal pour trouver des angles. Il y a 2 gradation d'angles et c est difficile a comprendre. Peut être utile pour les moulures mais pour ce qui est des travaux de construction, il faut repasser. Cher pour du plastic.

Fran: We were remodeling our batt and had some odd angles. The perfect tool for the project. It give you the angle and tells you how to cut it for inside or outside angles.
