The Graco 17H450 LineLazer V 3900 Standard Series is a gas-powered airless line striper designed for contractors who require higher production striping performance with the flexibility of dual manual guns. Powered by a Honda GX120 engine and equipped with Graco’s Endurance Chromex pump, this unit delivers consistent line quality for parking lots, commercial properties, and routine re-striping work.
Built for contractors handling larger jobs than entry-level machines, the 3900 Standard Series provides increased output, improved control, and enhanced job tracking through SmartControl and the LiveLook display. The dual manual gun configuration allows operators to stripe wider lines or switch between single and dual gun operation depending on the application.
With features like the EasyMark gun adjustment system, EZ Align wheel tracking, and QuikSelect gun selector, this machine is designed for accuracy, ease of use, and long-term durability.
This unit is ideal for contractors performing regular commercial striping who need more production capacity than entry-level units without stepping into hydraulic or automated systems.
