Frequently Asked Questions
- Q: How do I know if my car has a U-Hook arm?
- A: The U-Hook (or J-Hook) is the most common type. It looks like a flat, J-shaped metal hook. You can measure it: the open end is typically 9mm wide, and the “hook” depth is either 3mm or 4mm. If your arm has a side button, a pin, or a bayonet, it is a different type. Our product images clearly show the connector for comparison.
- Q: Does this one adapter really fit both 9x3mm and 9x4mm?
- A: Yes. Our universal U-Hook adapter is engineered with a tolerance range and locking mechanism that securely accommodates both 9x3mm and 9x4mm hooks. It has been tested on hundreds of vehicle models to ensure a firm, rattle-free connection.
- Q: What if my vehicle has a different connector type?
- A: For vehicles with specialty connectors (e.g., Pin Lock, Bayonet, Side Pin), we offer blades with those specific adapters pre-installed. Please check your vehicle’s wiper arm type or use our vehicle lookup tool to find the exact match.
