QuickDraw Pro Self-Marking Tape Measure
The QuickDraw Pro Self-Marking Tape Measure can lay down marks with the patented graphite marking system. It uses graphite sticks of lead, the same kind use in lead pencils, and the internal steel wheel at the bottom of the tape grinds to applies a graphite mark right where you want it. With the QuickDraw Pro, you can get up to 2,000+ marks per stick of lead. It is also working with damp, wet lumber and other wet materials.
