Starrett ProSite Miter Protractor Angle Finder with Two Laser Engraved Scales - Ideal for Carpenters, Plumbers, and DIY Home Improvement - 12 Aluminum - 505A-12

This is a great product with a simple design and I highly recommend it for anyone installing crown molding. Be sure and get the holster along with your purchase to protect your investment.

Im very happy with this.

Works great. Easy to read and very accurate.

I bought this tool to help with the calculations of crown molding cuts. It works very well. It takes all the guess work out.

Very effective

Excellent tool to have at work construction or carpentry

Great product, built to last. Dont know about some of the other reviews but mine was calibrated right on the money.

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.

It takes the guess work out of miter cuts. Im remodeling an older home and very few of the corners are square so this tool will make them look good.

Awesome tool
