9mm hook arms are the most common wiper arms on vehicles made before 2007. Most Chrysler, Dodge, Ford, GM, Honda and Toyota have this type of arm.
Position adapter shown in photo so “tooth” is on the bottom and align the opening on the adapter with the wiper center post.
Push adapter down onto center post of the wiper until an audible "click" is heard.
Rotate adapter slightly and insert the hook down through the opening.
Push adapter into the hook opening until there is a "click" when the hook engages the adapter.
