Flush rails are a popular feature found on many European wagons and SUVs. These rails typically elevate about 1-1.5 inches and often come with a small lip or bolt holes on the inside for easy mounting. One of the significant benefits of using flush rails is that it keeps the racks off the roof of the vehicle, thus preventing any potential damage to the paint. Mounting racks onto flush rails is a breeze, and they're just as durable as other rack styles, capable of handling similar weight loads. Whether you're hauling gear for a weekend getaway or quick day trip you can trust that your flush rail system will get the job done while keeping your vehicle looking sleek and pristine.
