    Question about the 'channels' mounted to my SUV

    Hope the pic turns out right side up.

    Anyhoo, how strong are these channels, for a lack of a better word? I was thinking of inserting a bolt, upside down, then through a metal crossbar so I can lash a kayak to the crossbars.

    I have a diagram I've drawn, if that explanation isn't clear enough. I'll try to get a good enough pic of it to post.

    Looks like it would work ok to me. I did something similar in the bed of my Nissan Frontier utilitrac system along the bed sides. I actually used a spring nut (not sure of the proper name) that is used in uni-strut. Check in the electrical section of any Lowe's, Home Depot, etc... Good luck

    Thanks. Can you describe this "spring nut" in a little more detail, please?

    You could use these to secure your crossbars and a bolt that is the proper length and it would be a much cleaner look. The bolt would be flush to the crossbar instead of having it the other way as your illustration shows. Just an idea anyway.

    I'd assume that these channels are used by the aftermarket rack companies to add crossbars to the vehicle. While you may not get into those set up's, you might check out the carrying capacity with their set ups. They will show a maximum carrying load, max will be 165lbs, but if they show lower, it is worth noting as that lower number is almost assuredly due to to the rail connection.

    Thanks.
    I see you have a bolt head in the channel. I'd consider as large a washer as possible on the bolt head, to maximize surface area. Maybe even spend a little time with a fender washer (essentially a very large washer with a small hole) and cut it down to size like an oval to slide back and forth and increase contact on the underside of the channel.

    Seriously, I would trust a square nut a bit more in that track.

    I'm not really concerned about the weight, as I'd be transporting a kayak that weighs less than 60 lbs, I'd be more worried about the lift caused by the wind.

    But yeah, point taken.

    Yes, that's a great idea. The bigger surface area the better. Thanks.

    So the spring is just to keep the nut from backing off?

    The spring in those is to hold the nut in place while you put the bolt in:

    Those probably won't fit into the tracks on your roof though, they're too thick. If you look at this picture of Yakima landing pads you can see the square nuts. You slide those into the track from the end, put your landing pad (or whatever) on top, and bolt it down. Question about the 'channels' mounted to my SUV-514x7ezqrzl._sl1000_.jpg

    You can buy the square nuts separately, you just need to verify the dimensions of your track: Replacement Anchor Plate "A" for Yakima LandingPad 1 (QTY 8) Yakima Accessories and Parts Y8810074
