thule Rapid Traverse roof rack with 50 inch square bars. Fits on the cab of my Toyota Tacoma 2003 regular size truck, where I just used one bar over the cab. Might fit other Toyota models of similar year, but dont know for sure. Thule does sell foot pack kits to adapt the towers to different vehicles- if you want to go this route. An end cap is missing on one of the bars. Everything works, but some surface scuffs visible. Unfortunately, I cannot provide a key.
