The Flyboy Accessories marking gauge makes your sheet metal layout work a snap. The gauge is easily adjustable from 1/4" through 6" and is infinitely variable. You simply set the edge distance that you want, insert the included fine line marker, and quickly and easily make a perfect line every time.
The gauge can be used to lay out rivet lines, bending lines, trim lines, or any other dimension that is needed relative to the edge of a sheet. It can also be used to mark the edge distance from the end of a tube, such as when installing control hardware, or it can be used on outside arcs too. Uses are limited only by your access to the edge of the workpiece.
The fine line marker ink is easily removed from the workpiece with rubbing alcohol, acetone, or other solvent. The marking process does not harm the workpiece whatsoever.
