THULE SquareBar 889704 Adapter, roof carrier

www.auto-doc.ie: Dear customer,
Thank you for your question.
The Thule 889704 adapter is designed to mount Thule crossbars onto raised roof railings— those are the roof rails that have a gap between the rail and the car roof (you can pass your hand underneath).
- It’s not a bike rack adapter.
- It’s used to mount crossbars onto raised rails on the roof of a vehicle.
In your case:
The Thule 889704 will not help, because it’s meant to attach crossbars to raised roof rails
It does not help with mounting bike racks to crossbars
Please check:
To install your Thule bike rack on the new car:
What kind of bike rack mount do you have? (T-track mount? Clamp-on?)
What is the shape/type of the new crossbars? (aero, square, with or without T-slots?)
Most Thule bike racks can:
Clamp directly onto crossbars
Or use T-track adapters (which may already be included)
To Conclude:
Thule 889704 is not needed in your situation. You likely just need to verify your rack’s compatibility with your new crossbars, or maybe buy T-track adapters if needed.
Feel free to contact us by chat.
Best regards,
the auto-doc.ie team
