The TRP Loose Wheel Nut Indicator, Dustite (Part No. 2281294) is a crucial safety and maintenance device for commercial vehicles running 41 mm wheel nuts. This long-reach model is designed to provide both a visual safety check and protection for the wheel nut.

As a Dustite indicator, it features an integrated cap that seals and protects the wheel nut and stud from road grime, water, and corrosion. The high-visibility Yellow color and clear indicator pointer allow for rapid pre-trip inspections: if the indicator is rotated out of alignment with its neighbors, it immediately signals that the wheel nut has loosened, preventing catastrophic wheel loss. Its Long Reach feature makes it suitable for applications where wheel nuts are recessed or require a longer visual presence.
