4ft by 4ft 45 degree Heavy Duty Aluminum Layout Tool

I am a Union Tilesetter,I always had to layout all my 45 degree floors with a Tile Helper,because there was the measuring and snapping of chalk lines to layout your 45% floor.For the last year or so,I have not done any Commercial Construction Work,everything I been doing now is on a much smaller scale,because I am doing residential homes.This 45 degree square is the perfect tool for this residential work ,because you are working by yourself a lot of the time,and you do not need a helper to snap chalk lines with you anymore.It not only is perfect for laying a 45 degree diagonal floor,its also great for squaring a floor in a room up ,if you plan on running the tile straight,and not on a diagonal.You go in a room, snap one chalk line off your full tile wall,then measure for your other full tile wall,lay your 45 degree square on your chalkline,and now your room is perfectly square.This is a great tool, I use it all the time,and its made really well,its heavy duty.And it also folds up,when you are done using this square.
