Review on Firecore 09031Magnetic Post Level: Effortlessly Accurate Alignment for Your Projects by Mike Devine

For installing corner posts in yard. It is very easy to use and functional. Two great features are the elastic strap that allows you to slide it over the frame so you don't have to hold it. If your bar is magnetic, it will have magnetic strips that will also keep it level. Another great feature is the chalk line holder. This plane can be used both horizontally and vertically. It comes with a five year guarantee.
