Patent attributes
A level includes a frame defining a web, a flange, and a gauging surface for placement on a workpiece. A magnetic retainer arrangement is secured to the frame laterally of the web and above the flange, and applies a magnetic force to a magnetically attractive workpiece through the laterally extending member. The web includes a lip that cooperates with the web and the flange to define a channel a facing in a direction opposite the gauging surface. The magnetic retainer arrangement includes one or more magnetic members engaged within the channel. The magnetic members are operable to maintain the level in engagement with a magnetically attractive workpiece, by virtue of a magnetic field that passes through the laterally extending member and that applies a magnetic force that acts on the magnetically attractive workpiece to maintain the gauging surface of the level on the workpiece.
