Can I Replace the U-Bolt Mounts on SportRack Cargo Box with Quick Grip Mounts Instead?

Question:

Hello, I have a SportRack Cargo box on Thule Wingbar rack. Can I replace the original U-Bolts on the SportRack cargobox for a more convenient and easy mounting system you have on the site? I have to remove it back and forth and I cannot do it myself with the U-bolts.

I absolutely understand your struggle and I remember having to mount and dismount the SportRack Horizon Cargo Box # SR7016 multiple times in a couple hours for a video. Fun times.

Unfortunately, even though SportRack is a Thule brand, the Replacement Quick Grip Mount Assembly # TH05738 cannot be fitted on your box. These special clamps need a special track design from within the box itself to work effectively and they are not like the U-bolt design like # TH05603 that only needs some drilled holes.

Based on my experience though, I do have some tips for you. Whenever I have to mount cargo boxes by myself for a video, I prep three things: a towel, some tape, and the Rightline Gear Moki Door Step # RL100660.

The towel goes on the roof and is to catch all the bolts that I inevitably drop, or to keep them handy. The tape is for the mounting hardware usually underneath the box. I tape them in place with some painters tape while I position or tighten the other pieces of hardware. Finally, my Moki Door Step # RL100660 is so that I can get up there in the first place. It gives me that extra height and stability to reach into my cargo box and mount things down.

It's not a perfect solution, but the other option is to consider upgrading to a box that comes with those clamps like the Thule Pulse # TH614.
