Will this work on my existing roof rails?

This is a universal crossbar designed to fit most round and square roof rail profiles. Test-fit it on your system before finalizing purchase — rail diameters vary slightly across brands and model years.

What mounting hardware do I need?

The crossbar itself ships as a bare assembly. You'll need to source clamps or brackets that match your specific roof rail system — those typically come with your rails or are sold separately by the rail manufacturer.

Does the black finish need any prep or maintenance?

The hard-anodized coating is ready to install as-is. Rinse it with water and mild soap occasionally to keep salt spray and grit from building up, especially in coastal or winter conditions.
