The Ultimate Layout and Marking Tool

This wonderful tool is used to mark the location of hooks on the back of a mirror, piece of art or a shelf.  Those items that have to be hung by 2 hooks.  The red pieces slide to mark the locations from the back of the art or shelf and then the level is taken to the wall and the marks can then be transferred and made level.  

Level is available in 36" size.
