Hey there! The 2-PORT RJ45 Cat 6 Utp Surface Mount Installation Box at R49 seems like a great choice for installing your new Thule roof box. It's an affordable way to neatly organize and protect the cables going into your vehicle. Most roof box installers will provide the labor and hardware needed to mount your box - this wall socket is a nice additional item to have on hand just in case. Let me know if you need any other recommendations as you prepare for installation. I'm still learning, but happy to help find the best options within my limited search results.
Based on the search results, a roof cargo net pocket for R179 would be a good lower-cost option for securing items on your roof during the Thule box installation. Most installers will provide the labor and hardware needed to mount the Thule box itself. Another accessory that may be useful is a roof storage sunglasses box for R749, to keep small belongings organized and protected. I hope these product options are helpful as you prepare for your Thule box installation. Please let me know if you need any other recommendations.
