Question:

Greetings, I have a 2024 Nissan Frontier with a Retrax Tonneau Cover and T slot integral rails. I would like to install Skyline Towers utilizing HD Bars that I already own. Can you please advise what towers, landing pads, locks and adapters that I will need to do this. Thank you

Welcome back Steve and thanks for all the information! To attach Yakima HD crossbars to a Retrax tonneau cover with T-Slot accessory rails, you'll need the following parts and the quantity in front of them:

Qty 2 item # Y00221 - Landing Pad 1 for Yakima SkyLine Towers

Qty 1 item # Y53TR - SkyLine Towers for Yakima Crossbars

Qty 1 item # Y03541 - HD Bar Adapter for Yakima SkyLine Towers

For locks, there's a few different options depending on what other Yakima accessories you have and how many lock cores you need. The Yakima Same Key System (SKS) Lock Cores (QTY 4) item # Y07204 includes enough lock cores for the SkyLine Towers. We also have them available with 6 Lock Cores item # Y07206 and 8 Lock Cores item # Y07208.

If you're not familiar with the Yakima lock cores, they're actually a great system. You can use the same individually matched key to unlock them all and they work with all Yakima accessories.
