The Graco 258699 ThermoLazer 300TC Thermoplastic Striping System with 4-inch SmartDie II is a high-production handliner designed for contractors who need increased capacity, efficiency, and performance on thermoplastic striping jobs.
Featuring a larger 300 lb material kettle, the 300TC allows for longer striping runs with less downtime for refilling—making it ideal for medium to large projects. The SmartDie II system delivers superior line quality with precise control, while the EasyGlide Wheel Mount System ensures smooth maneuverability comparable to a LineLazer striper.
