The TRP Loose Wheel Nut Indicator (Dustite) Part No. 9507892 is a critical safety device designed for commercial vehicles. These high-visibility indicators are fitted onto wheel nuts and serve two crucial functions:

Safety Indicator: By positioning all indicators in a recognizable pattern, drivers and maintenance staff can instantly spot any movement. If an indicator is misaligned, it clearly signals that the wheel nut has loosened, enabling quick corrective action and preventing potentially dangerous wheel loss.

Dust Cap: The ‘Dustite’ design incorporates a cap that covers the wheel nut, providing protection against weather, corrosion, and dirt ingress. This helps to extend the lifespan of the wheel nuts and ensures easier removal during maintenance.

As part of the TRP safety range, these indicators contribute significantly to fleet safety and compliance with roadworthiness checks.
