Unfortunately, Thule never created a fit for the 400-series towers on '13-18 year range Altimas by Nissan. If you'd like us to confirm that the footpack you have is a 400-series, feel free to contact us directly by selecting online/direct on the contact sheet and including a clear picture
. There are other setups available for your vehicle, like Yakima's BaseLine series
, that would be perfect for your vehicle and we are always more than happy to get you some information regarding all possible setups!
