The 424-836 Glassbead dispenser 6" is a complete dispensing system 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 6-inch dispenser applies reflective glass beads onto freshly painted lines with a 6-inch application width, creating immediate retroreflectivity that significantly enhances nighttime visibility for drivers. Glass bead application is essential for traffic markings on roadways, parking lots, and other surfaces where visibility in low-light conditions is required for safety.
The dispenser system includes a storage hopper, feed mechanism, and dispensing nozzle that precisely deposits beads into the wet paint stream immediately after application. The 6-inch width designation indicates the bead application pattern width, which matches common line striping widths for parking lot stalls and roadway markings. Proper bead application requires correct positioning relative to the spray gun, consistent flow rate, and reliable activation synchronized with the paint spray. Over time, bead dispensers may experience wear in the feed mechanism, clogging in the dispensing nozzle, or damage to mounting components. A malfunctioning dispenser can result in inconsistent bead application, wasted beads, or reduced reflectivity that fails to meet safety standards. Replacing or installing a complete bead dispenser system restores proper bead application capability, ensuring that freshly striped lines achieve the required retroreflectivity for safety compliance. This dispenser is manufactured to original equipment specifications for correct fitment, reliable bead flow, and consistent application on compatible models.
| Retroreflectivity | Applies reflective glass beads into wet paint for nighttime visibility |
|---|---|
| Precision application | Delivers beads directly into fresh paint stream for optimal embedment |
| Safety compliance | Helps ensure traffic markings meet required reflectivity standards |
| Inconsistent flow | Bead application is uneven, sparse, or missing along the line |
|---|---|
| Clogging issues | Dispenser nozzle repeatedly clogs despite cleaning |
| Feed mechanism wear | Worn auger or metering components affect bead delivery rate |
| Mounting damage | Bent or damaged mounting brackets affect alignment with spray gun |

When servicing the glass bead dispensing system, these additional components are frequently inspected or replaced at the same time.
The storage container should be inspected for damage or contamination that may affect bead flow.
The metering mechanism and control linkage should be checked for proper adjustment and wear.
Proper alignment between the bead nozzle and spray gun is essential for consistent bead embedment.
