"Prepare your vehicle for overhead cargo storage with this pair of Apex Aluminum Roof Cross Bars. Manufactured from high-strength, lightweight aluminum, these cross bars will never rust and will hold up well in all elements. This set of cross bars includes two bars. They fit side rails spaced 35-1/2"" to 37-1/2"" apart, measured from the inside, and have a shared weight capacity of 165 lbs. Anti-theft locks prevent unauthorized tampering, and installation is easy - simply clamp them on to your existing raised side rails for immediate use. The center rubber grips can be removed to allow T-bolt accessories to mount right to the crossbars."
