A cross between full and trade rails, 3/4 rails, along with an optional roller kit, assist with easy rear loading of large and awkward items while still providing load security at the front of the rack. Also designed for rear folding rooftop tents, subject to tent width. Attaching quickly and easily to the dovetail extrusion around the rack’s perimeter, the range of optional rails mean you can have a full guard rail system on or off in just a few minutes!
