Will these mount to the factory roof rails on my Compass?

These bars are designed for factory mounting points — no drilling. Test-fit before any permanent installation to confirm your roof configuration matches the attachment method.

What cargo accessories can I attach to these cross bars?

Standard roof-mounted systems like cargo baskets, boxes, and bike racks will clamp across the bar profile. Verify your accessory's clamp width matches the cross bar dimensions before purchase.

Do I need to prep or seal these before installation?

The black finish is ready to install as-is. Wipe clean before mounting to remove any dust or oils from the factory packaging.
