Four-wheel chalker, with no flat tire

Stripe flawless diamonds in record time with this ProCage field line marker—a heavy-duty chalk line maker engineered for crews that demand pro-level results. The green powder-coated hopper holds a full 50 lbs of chalk, so you can tackle batter’s boxes, base paths, and outfield arcs without constant stops. Four puncture-proof no-flat tires glide over turf and infield mix, while the steel axle keeps the ride steady on rough ground.

An easy hand lever adjusts flow from 2- to 4-inch widths, giving you true “4 × 50” capability (4-inch stripes out of a 50-pound hopper) whenever wide, bold lines are required. A white guide stripe on the lid keeps the carriage perfectly aligned, and an ABS-metal agitator prevents clumps so chalk pours smoothly start to finish.

Built entirely from galvanized steel.
