Product Uses & Advantage
Uses:
Roof Rack Systems – Functions as the primary release mechanism for quick-mount bike, ski, or cargo carriers, enabling easy loading/unloading while maintaining secure attachment during transit.
Truck Bed Accessories – Provides latching functionality for sliding tonneau covers and retractable truck bed racks in commercial and recreational vehicles.
Trailer Hitch Racks – Ensures stable locking for hitch-mounted cargo platforms, preventing accidental release during highway speeds or off-road conditions.
Advantages:
High Load Capacity – Reinforced hook geometry and alloy selection support 100+ kg dynamic loads without deformation, even under vibration and shock.
Corrosion Resistance – Anodized (aluminum) or electroplated (zinc) finishes protect against road salt, UV exposure, and humidity for long-term outdoor durability.
User-Centric Design – Smooth lever action with tactile feedback allows single-handed operation, while integrated safety locks prevent accidental release.
