I like steel. It's tough and cheap. It makes life better. But I don't like steel framing squares. They rust and rust doesn't make life better. I like aluminum far more. In 5 years you'll be glad you bought an aluminum square instead.

It's a great durable square. The numbers were very easy to read. I purchased this item as I am a new homeowner and I think it's perfect for homeowners to use when performing carpentry tasks that the wife gives you. Amazon had the best price for it. I like buying products that were made in the USA too.

On a side note, I'm not sure who shipped it, but they put a sticker on it that read Amazon but didn't peel right off. It was more of an inconvenience than anything.

I've used the aluminum square for the same reason as other reviews. I was a rough carpenter, finish carpenter, cabinetmaker for a long time. Just getting into furniture making. I was trying to square up a new combination miter saw and couldn't get it quite square to the fence. I even used brass shims and couldn't get better than .06".

Finally, I took the square and drew a line across a piece of 16" ply. Then I flipped it and tried to draw over the same line. What I found was, the ends of the square, after years of drawing lines and using as a straight edge and cutting guide had worn off and were slightly rounded. Still, after 15 years of good service, I am ordering another today.

It is all you would expect a square to be. When you get any square, lay it up against the edge of a countertop and strike a line, then flip it over so the leg is pointing the other way and strike another line next to the first line. are they EXACTLY the same/parallel??? If not it's not square....!

Nice square, a lot of info on it, but lacks the 1/12 markings and no hole to hang. Very light and easy to handle. Hope it is sturdy.

This came wrapped in bubble wrap which was taped on with clear tape to the square. The tape, for some reason, was directly on the square, and when removed left a sticky residue that will not come off! Tried, acetone, good gone, and paint thinner to no avail! So, needless to say, when I'm cutting things like paper, or shelf liners, I can only use one side because the other side will stick to the material!

Also, compared to my Stanley tape measure, it seems to be about 3/64" off. See photo.

It came on time and was as expected. Would have been better if it had a pre-drilled hole to hang it on the wall, but I added it myself. Light weight and feels sturdy enough.

Good light weight item. Be careful not to bend as it is not ridgid enough to withstand much pressure. Otherwise, a good tool to have in your possession.
