Checkpoint Checklink 19 mm Dark Grey Wheel Nut Indicator & Retainer

Checkpoint Checklink 19 mm Dark Grey Wheel Nut Indicator & Retainer

The Checkpoint Checklink 19 mm (Catalog Index: CHP-CLDOG19) is an essential wheel security accessory manufactured by Checkpoint Safety for light commercial vehicles (LCVs), delivery vans, utility trailers, 4x4 vehicles, and specialized transport equipment. Designed to fit 19 mm wheel nuts, the Checklink links adjacent nut pairs together via an S-shaped polymer bridge, providing active mechanical retention against nut backing-off while allowing instant visual verification during pre-trip driver walk-around checks.

Key Performance & Structural Highlights

Dual-Action Safety (Indicator + Retainer): Connects adjacent 19 mm wheel nuts to create mutual mechanical resistance against vibration-induced backing off, while providing clear visual indication if a nut rotates out of alignment.

Thermal Overheating Early Warning (125°C): Formulated from an engineered polymer designed to soften and distort at 125°C (257°F), alerting drivers and fleet technicians to hub overheating caused by binding brakes or failing wheel bearings.

Durable & Bio-Friendly Polymer: Built from high-strength virgin polymer with a dark grey (military khaki) finish that withstands harsh weather conditions, road salts, and chemical cleaning agents.

Streamlined Fleet Safety Compliance: Simplifies daily vehicle walk-around inspections and supports fleet compliance with road safety standards (DVSA, FORS, and ISO fleet safety guidelines).

Tool-Free Quick Installation: Snaps easily over adjacent 19 mm hex nuts without requiring specialized tools or wheel dismounting.
