Review: Hubby happy with the blue book - Bought this for my husband. Delivery was prompt and item was as expected. Hubby was so happy with the included blue book. Review: Unbeatable for framing work - This is not a replacement for an adjustable combination square and is not suitable for fine work, but for its intended use in framing work it is brilliant. The pencil notches for marking lines parallel to the edge of a board are very useful when ripping wood and the protractor feature is surprisingly usable (though again, not really for marking off 3.25 degrees!) The wide base makes this convenient for checking joints for plumb as it will stand on its own quite securely; this base also makes a really solid rest for when you want to mark a cutting line at 90 degrees - it hooks over the edge of a standard CLS 2x X timber perfectly and gives a far more positive result than a standard combination square (the full length of the side of the square being in contact with the timber really helps here too.) I have not yet used the square for the purpose for which I bought it (laying out rafters for my current project) but hope to do so soon - the accompanying "blue book" seems fairly comprehensive and I'm confident this square will make my life a lot easier when the time comes. Overall the square is well made from nice thick metal and very nicely finished. My only criticism would be that the black paint applied to the markings wasn't particularly thorough; as the markings themselves are deeply recessed into the metal there is no issue in practice. Edit: I have since used it to make rafters and very much more and it was excellent. Once you've figured out the desired roof pitch it's so simple to get every cut at the right angle - not just for rafters but things like barge boards, sheathing, lining, interior trim etc. Worth every penny. ## Features - Multiple Gradations: Gradations Included For Marking Common, Hip, Valley, And Jack Rafters; Useful For Determining And Marking Angles And Making Square Cuts On Boards - Features: Pocket-Sized Swanson Blue Book, A Comprehensive Guide To Help Workers Make Correct Angle Cuts For Any Pitched Roof - Includes: Features Common To 5 Different Tools (Try Square, Miter Square, Saw Guide, Line Scriber, And Protractor) Making The Speed Square Something That Belongs On Every Tradesman'S Tool Bench - Easy To Use: 1/4-In Spaced Scribing Notches And The Diamond Cutout For Easy Rafter Seat Cuts And Scribing The Most Common And Popular Stud Widths ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00002255O | | Best Sellers Rank | #9,433 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #11 in Carpentry Squares | | Brand | Swanson Tool Co., Inc | | Brand Name | Swanson Tool Co., Inc | | Color | Blue | | Colour | Blue | | Country Of Origin | USA | | Customer Reviews | 4.8 out of 5 stars 16,716 Reviews | | Global Trade Identification Number | 00038987001017 | | Graduation Range | 1/8 Inches | | Graduation range | 1/8 Inches | | Included Components | Swanson Tool S0101 7-inch Speed Square Layout Tool with Blue Book | | Item Dimensions L x W | 20.3L x 2.5W centimeters | | Item Thickness | 11 Inches | | Item Type Name | Swanson Tool S0101 7-inch Speed Square Layout Tool with Blue Book | | Item Weight | 0.5 Pounds | | Manufacturer | Swanson Tool | | Material | Metal | | Material Type | Metal | | Model | S0101 | | Number of Items | 1000 | | Number of Packs | 1 | | Part Number | S0101 | | Product dimensions | 20.3L x 2.5W centimeters | | Style | 7" Speed Square | | Style Name | 7" Speed Square | | UPC | 038987001017 | | Unit Count | 1 Count | ## Product Details - **Brand:** Swanson Tool Co., Inc - **Colour:** Blue - **Graduation range:** 1/8 Inches - **Material:** Metal - **Style:** 7" Speed Square ## Images ![Swanson Tool Co S0101 7 Inch Speed Square, Blue | 7-inch aluminum double sided carpenter rafter square triangle tool, die cast for true accuracy and durability - Image 1](https://m.media-amazon.com/images/I/71V66GuEE-L.jpg) ## Questions & Answers **Q: In what country is this product made?** A: We proudly make all of our Swanson Speed Squares here in the United States. **Q: Can you mark 45 degree cuts** A: 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 **Q: Which size (7 or 12) would be best for a re-roofing project?** A: 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. **Q: Does the ruler also have units of measurement of centimeters?** A: 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 ## Customer Reviews ### ⭐⭐⭐⭐ Hubby happy with the blue book *by S***Y on 15 March 2021* Bought this for my husband. Delivery was prompt and item was as expected.
