The 424-816 2nd Gun Kit 4-6" Line Width is a complete auxiliary spray gun assembly designed for use on a wide range of PowrLiner striping machines, including the 8900 series, 6900 series, 6950 series, 4900 series, 4955/6955/8955 models, and the 4500 and 5500 series. This kit enables operators to configure their striping machine for dual-line applications, allowing two parallel lines to be applied simultaneously in a single pass. The kit is engineered to provide adjustable line spacing between 4 and 6 inches, accommodating common parking lot stall striping and roadway lane marking requirements.
Dual-line striping significantly increases productivity by eliminating the need for a second pass to apply the second line. The second gun kit includes all necessary components for installation, including the spray gun assembly, mounting hardware, control cable or linkage, and fluid connections. Proper setup ensures that both guns operate in unison, delivering consistent line quality and spacing across extended striping runs. Over time, components of the second gun system may experience wear from use, or the kit may need to be reinstalled after machine servicing. Replacing or installing a complete second gun kit restores dual-line capability with properly matched components designed to work together. This kit is manufactured to original equipment specifications for correct fitment, reliable operation, and consistent line spacing on compatible models.

When setting up or servicing a dual-gun system, these components are frequently inspected or installed alongside the second gun kit.
Both guns should be matched for consistent operation and pattern quality across both lines.
The fluid distribution system should be inspected to ensure equal flow to both guns.
Synchronization mechanisms should be adjusted for simultaneous gun activation.
