We proudly make all of our Swanson Speed Squares here in the United States.

Can you mark 45 degree cuts

Hi Henry, Absolutely, you can mark 45-degree cuts with our famous Speed Square! We manufactured it as a right triangle with that use in mind - its hypotenuse (the long side of the triangle) is an exact 45-degree angle. Thanks for your interest in our square! The Swnason Team

Which size (7 or 12) would be best for a re-roofing project?

Typically a framing square would be the most helpful with a roofing project. But if I had to choose one or the other, I guess the 12. While 7 is standard, it will not span the short dimension of the shingle.

Does the ruler also have units of measurement of centimeters?

Hi Tomer, Great question! This Speed Square, our model # S0101, does not include metric units of measurement. Our Metric Speed Square, model # NA202 (and available on Amazon.com) does have metric units of measurement. Hope that helps! The Swanson Team

Very good purchase, top class purchase. Both items are above and beyond the call of duty. Swansons have the reputation for the best speed squares while the 6 inch adjustable square is well thought out. The scribing pin is SCREWED in. No lost scribes any more.
