The Rhino-Rack Vortex Cap/Topper Trackmount Roof Rack system is permanently fixed to either a pickup Cap/Topper or hard top tonneau. This system uses the Rhino-Rack Vortex black bar with tracks to complement the sleek stylish lines of your pickup while still incorporating the Rhino-Rack strength and durability that we are renowned for. The great benefit of this roof rack system is the ability to slide your cross bars along the track to accommodate various sized loads.
Got two products that were missing parts. After receiving the 2nd rack with missing parts; I was told by customer service to contact Rhino Rack directly to get the missing parts. It has been a month since ordering. Waiting on Rhino Rack to respond. The rack (besides missing parts) seems to be just like all the reviews you see on the web.
