Do these bolt directly to my CR-V's roof rails, or do I need to drill anything?

They mount at factory roof rail points—no drilling. Just bolt them down to the existing channels using basic hand tools.

Will I need additional hardware to mount a cargo basket or bike rack?

The crossbars themselves come as pictured. Mounting hardware for accessories (cargo boxes, bike racks, etc.) depends on what you're attaching—confirm compatibility with your chosen accessory before purchase.

What's the warranty on these crossbars?

Warranty details are handled by ModSupply's standard return policy. Contact support directly if you receive a defective set or want coverage specifics before ordering.
