The Modified Square

the modified square

This odd looking “modified square” intrigued me when I first saw it. Made in McKees Rocks, PA. Great for structural steel, pipe fitting, sheet metal work and carpentry. Designed with 4 – 90 degree angles for squaring and marking work points around an edge or insert. 1 9/16″ opening by 3 1/2″ deep. Used for stair stringers and stair spindle layouts plus 2×4 notch outs. Zero/zero center finding ruler for your work materials. Finds the depth for striking nails on an overhanging edge or insert. You can also transfer work points from far side to near side for layout purposes. Measures height and depth simultaneously. It’s like the swiss army knife of squares!

    A very intersting square for layout work!

    The Modified Square Company has a web-site, that explains the uses of this tool in detail, with a on-line instructional video included.

    Boy, he must have spent countless hours thinking this tool up!

    Can not say that I have ever seen stair stringers “cut out”, like the one’s he uses in the demonstration.

    Depends upon what part of the Country you are from and the applicable building codes.

    Just like well over a 100 plus years ago, when someone invented the framing square.

    A very dependable and accurate tool, when used in trained and experienced hands.

    It was and still is a very accurate calculator, right up there with the engineer’s slide ruler.

    You real do not need a electronic device to do you calculations, which indeed does speed things up, but in some cases it is mindless!

    Proud to say I am “Old School” and don’t lecture me on “new math”, where 2+2=1!

    I believe this new square, will be a good sale item for HJE Company and should turn a fair profit.

    Did not know that this Company exisited, until I saw it on your posting!

    Hope the “flu bug” that hit your store, is D..E..A..D.. and will not return for many, many years!

    I have one of these modified squares and it is a wonderful tool. I use it so often, it’s second only to my hammer! Recently I’ve been remodeling my house due to a flood and i have used the modified square extensively during re-construction of just about everything!
