2011 Jeep Grand Cherokee with Flush Roof rails
Flush roof rails on a Jeep Grand Cherokee. Flush roof rails run along the side of the roof and have no space between them and the roof of the car. Flush is kind of a mis-used term, they often are not particularly flush, the defining feature is that they do not have space underneath for cross-bars to wrap around the rails. The fit hardware for an aftermarket rack typically bolts to or clamps onto the flush rail.
