Roof Racks & Truck Racks
There is a common misperception that the plastic strips that run front-to-back on the roof of many modern vehicles is a rain gutter that can be attached to. For rack purposes, this is not a rain gutter. In the rack world, that is a "Naked Roof" car; the most common fit solution for this sort of roof is a clip fit.
Clip Fit roof racks tension around the door frame of cars that have no pre-installed attachment points. These cars can be described as "Naked Roof" or "Bare Roof."
Clip fits require two components; the tower is fairly universal, while the clip or fit kit adapts the tower to fit specific vehicle(s). These fits require precision measurement to ensure correct installation.
