Rated 4.7 out of 5 by 13 reviewers.
Rated 5.0 out of 5.0 by Incredible product Received this as a Christmas gift and I have to say it's the best one I've ever gotten. It's perfect for mixing dough and batters that a normal hand mixer can't handle. I can't wait to get some of the attachments and try them out too. December 17, 2014
Rated 5.0 out of 5.0 by Alternative Use in Home Kitchen I was in the store shopping for stainless steel sheet or stove backsplash tiles to store magnetic spice jars inside a pantry door. Options on the site were not present in the store, but walking by the yardsticks & such I decided to test if they would hold magnets. Aluminum ones didn't, this stainless one did! I purchased two, and screwed them to the hollow-core wooden pantry door through the existing holes in the metal, using plastic washers because the holes were larger than my screws' heads. The shorter legs partially overlap at the top of the door. The L-shape actually works better than what I had wanted, for less than sheet metal tiles and a mere fraction of the cost of products made for the purpose of magnetic spice storage. If I need more space, I can add more rafter squares or yardsticks inside the first two. January 16, 2013
Rated 5.0 out of 5.0 by Great Quality Square!!! I am very pleased with this tool. It's a nice heavy duty piece of equipment. It should hold up a long time. The best part is the price! Honestly I was not expecting too much. I was pleasantly surprised. You cannot go wrong and Home Depot is great to work with. September 22, 2015
Rated 5.0 out of 5.0 by A requirement for any major carpentry work I bought the steel square last year when I started doing major work on my house. It has been there every step on the way. Building new walls, marking perfect squares for cutting vent holes, replacing floor sections, building stair stringers, etc. It has held up great, and look forward to many more years of service out of it. Only problem I have had is that it is starting to rust in places, but when you have sweaty hands, and handle steel, it can lead to rust, but doesn't affect the workings of the square. I will be using it when to mark my roof rafters when I put a roof on my porch. I would recommend this for anyone. They are easy to learn and the uses are endless. I also recommend getting the stringer gauges for constant, accurate markings. June 28, 2015
Rated 4.0 out of 5.0 by Seems great. Pythagoras sez: a^2 + b^2 = c^2. The corner-to-corner dimension of a 16 x 24 square should be 28-27.02/32 inches. Fortunately, Home Depot stocks tape measures right next to the framing squares. Probably a good idea to check that the legs match the tape measure first, but you can easily walk to the register knowing that the framing square you have selected is as square as you need it to be.

Rated 3.0 out of 5.0 by Typical It's a square. It seems pretty square and doesn't seem to have any issues. January 19, 2015
Rated 5.0 out of 5.0 by It's a steel rafter square. Duh! It is shaped as a right angle. That 's why it is called a square. It has tables for calculating rafter lengths stamped on the side. That's why it is a "rafter square". They usually get replaced when they drop on concrete from 30' up or get run over by a truck. Otherwise, the one from my grandfather's tool box would still be serviceable. September 30, 2014
Rated 5.0 out of 5.0 by good purchase Perfectly straight. Helped me and my wife finish a set of stairs. July 23, 2014
