I have a couple of different telescoping carbon fiber poles that I use for Pole Aerial Photography, a 11m and 12.5 meter pole. I normally keep one of the poles in the back of my Toyota, but it's always in the way, and I had a feeling that it's going to get broken if I continued to transport it that way. I have 2 Big dogs that ride back there, and I wanted to clear the space, but still have it with me at all times. I decided to build a PVC container that is mounted to my Yakima roof rack securely, with he ability to lock the carbon pole inside. Both poles have a rubber end cap, and they individually fit into a 2" PVC tube. I allocated the proper tubing from the Home Depot with end caps, and used some old rack parts to mount it to the Yakima.
I primed and painted the PVC black to match my car and rack. The front end-cap is clued on with a bolt and lock nut securing it in place.
The back end-cap is secured with a larger bolt where the nut is hand tightened.
I drilled a hold through the bolt large enough to put a Masterlock on to prevent anyone from peeking inside without the key.
I put a small bolt on the end cap of the carbon pole so I would have a way to pull it out from the pipe.
The 12.5m carbon pole fits into the tub with about 1" to spare.
The PVC tube was drilled to enable 2 bolts a couple of feet up from each opening to mount to a standard Yakima rack plastic mount. The enables me to lock the PVC tube to the rack a 2 mount points.
Here's the complete rig mounted on the Highlander, and ready to go for the summer. I always will a pole with me, and just have to remember to bring the camera!
