Open rail roof racks, also known as raised rails or open rails, offer a versatile and convenient solution for mounting racks onto vehicles. These rails feature a clear space between the roof and the rail itself, allowing for a greater degree of flexibility in fitting racks. The most common method for attaching racks to open rails is through a basic clamp system, such as Rhino-Rack’s RX100 legs or Prorack/Yakima’s K328 fitting kit. These clamp systems are widely available and easy to install, making them the preferred choice for many vehicle owners.

One of the key benefits of open rail roof racks is their versatility. With various mounting methods available, users have more options when it comes to bar spread and fitting different types of racks. Additionally, open rails allow for the use of rail bars or Stealth Bars, which provide a low-profile fitment that doesn't compromise the aesthetics of the vehicle. This makes them an ideal choice for individuals who use their racks infrequently or prefer a sleeker look for their vehicle.

However, it's important to note that while open rails offer versatility, some rail types may have specific profiles that limit mounting options. In some cases, open rails may also reduce the maximum carrying capacity of the vehicle's roof. For those planning on off-road use or carrying heavy loads, removing the rails and installing an alternative, such as a track system, could provide a better solution. Overall, open rail roof racks provide a convenient and flexible way to transport gear and equipment while offering options for customization and aesthetics.

Aero bars are not only aesthetically pleasing but also offer practical advantages, combining style with functionality. Their sleek, low-profile design not only enhances the vehicle's appearance but also minimizes noise while maximizing fuel efficiency. They are easy to install, featuring a built-in T-slot that allows for quick attachment of various accessories such as kayak carriers or bike racks. Additionally, the inclusion of locks provides added security and peace of mind for users.
Whether opting for the Aero Flush for a stylish complement to the vehicle, Aero Through for expanded carrying capacity, or Aero Rail for compatibility with roof rails, these bars offer versatility and convenience for outdoor enthusiasts and travelers alike.
