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.

HD (Heavy-Duty) roof racks feature a robust and durable design engineered to handle heavier loads and withstand rugged conditions. These racks typically incorporate thicker and stronger crossbars, along with reinforced mounting systems, allowing them to support bulky items such as rooftop tents, construction materials, or large recreational gear like kayaks and snowboards.

HD bars are ideal for outdoor enthusiasts, tradespeople, or anyone requiring a reliable roof rack solution for off-road adventures, construction work, or frequent heavy hauling. While they may sacrifice some aerodynamics compared to sleeker options, HD bars prioritize strength and versatility, making them a dependable choice for demanding tasks and challenging terrains.
