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.

Me es muy útil. De buen tamaño para usarlo también como guía para sierra circular asi como también su grosor es ancho ya que he visto otras escuadras rápidas muy delgadas. también es útil para que asiente bien la madera cuando vas a poner un tejabán. Estoy satisfecho con el producto.
