Patented pair of flip-down loads. They can be lowered completely to facilitate loading/unloading operations or to reduce wind resistance during times of unuse. When they are partially lowered, they slide over the bar to fit the width of the load, while they lock when raised to keep the transported items securely in place. They are mounted in the rear channel of the ProBar bar leaving the upper one free which can therefore be used for other accessories. Made from an advanced long lasting polymer Height: 17 cm.
