424-841 2nd Gun Kit 12" Line Width is a complete auxiliary spray gun assembly designed for dual-line striping applications on compatible PowrLiner machines. This kit enables simultaneous application of two lines with 12-inch spacing, increasing striping efficiency for wider parking lot stalls and roadway applications. A properly configured second gun system allows operators to stripe two lines in a single pass. This kit restores dual-line striping capability on compatible units.

The 424-841 2nd Gun Kit 12" Line Width is a complete auxiliary spray gun assembly that adds dual-line striping capability to compatible PowrLiner machines. This kit enables operators to apply two parallel lines in a single pass, significantly increasing productivity for parking lot stall striping, roadway lane markings, and other applications that require paired lines with 12-inch spacing. The kit includes a complete spray gun assembly, mounting hardware, control linkage, and fluid connections necessary for installation.
The 12-inch spacing configuration is a standard dimension for many parking stall layouts and roadway applications. When properly installed and synchronized with the primary gun, the second gun system allows the operator to complete striping jobs in half the time compared to single-gun operation. The kit is designed for straightforward installation on compatible models, with adjustable components that allow precise alignment of the second gun relative to the primary gun. Proper alignment ensures that both lines maintain consistent spacing throughout the striping run, producing professional results with clean edges and uniform width.
Over time, components of an existing second gun system may wear from repeated use, sustain damage from impacts, or become misaligned during machine servicing. A worn or damaged second gun can produce inconsistent line spacing, uneven pattern quality, or unreliable activation. Replacing the second gun kit restores full dual-line functionality with components that are matched for reliable operation. This kit is manufactured to original equipment specifications, ensuring correct fitment, consistent activation synchronization, and accurate 12-inch line spacing on compatible models.

When setting up or servicing a dual-gun system with 12-inch spacing, 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.
