Seymour's Z-604 STRIPE Traffic Marking Machine is an easy-to-use solution for marking concrete and asphalt.
The machine creates even 2"-4" lines, and from a standard 20 oz can, you can get get up to about 250' of length with the marker set at 4" wide.
The design of the traffic marker makes it easy to manipulate, while providing extra space for refills. Now you don't need to keep running back to the truck when one can is empty. Change the can on the go.
