A-Square 4 ft. x 4 ft. Heavy Duty 45° Folding 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.

great layout tool, esp. if your laying out tiles to go in diagonal.
