Product Information

Full details

The Thule Roof Box U Clamp Brackets are essential for outdoor enthusiasts and travelers looking to securely attach a cargo box to their vehicle's roof bars. Designed for versatility, this 80mm wide-fit bracket set provides a reliable mounting solution for Thule, Halfords, and Mont Blanc roof boxes, making it an ideal choice for replacing worn hardware or keeping a spare set on hand. While these clamps offer robust compatibility, users should verify their specific roof bar width to ensure a proper fit before installation.

FAQs

Are these compatible with all Thule roof boxes?

These brackets are compatible with most standard Thule roof boxes that utilize a U-clamp mounting system, provided the attachment holes align with an 80mm width.

Can I use these with aerodynamic wing-style roof bars?

These are primarily designed for standard bar profiles. If your wing bars are wider than 80mm or have a unique shape, they may not fit.

Do these brackets include locks?

No, this kit includes the mounting hardware (U-bolts and nuts). It does not feature built-in security locks.

How often should I check the brackets?

It is recommended to check the tightness of your brackets before every trip and periodically during long-distance travel.

Is the 1-year guarantee transferable?

The manufacturer guarantee is subject to the terms of the original purchase; please retain your proof of purchase.

Troubleshooting

Bracket feels loose after tightening

Check that you are using the provided load plates and ensure the nuts are tightened evenly on both sides of the U-bolt.

U-bolt does not fit around the roof bar

Verify that your roof bar width does not exceed 80mm; if it does, this specific bracket model is not compatible.

Difficulty threading the nut onto the bolt

Clean the threads of any grit or dirt and ensure the bracket is aligned perfectly perpendicular to the base of the box.

Pros and Cons

Pros

  • High compatibility across multiple brands including Thule and Halfords
  • Sturdy construction ensures cargo box stability during transit
  • Easy installation process suitable for DIY mounting
  • 1-year manufacturer guarantee for peace of mind

Cons

  • Specifically sized for 80mm bars; may not fit extra-thick aerodynamic bars
  • Does not include locking mechanisms
  • Requires manual tightening which needs periodic checking

Setup, Compatibility & Care

To install, slide the U-bracket up from underneath your roof bar and feed the threaded ends through the pre-drilled holes in the base of your cargo box. Secure them using the provided plates and hand-tighten the nuts until the bracket is firmly gripping the bar. To ensure longevity, keep the threads clean and free of debris. If you frequently travel in coastal areas or during winter months, a light application of silicone spray or anti-corrosion lubricant on the threads will prevent seizing and make future adjustments much easier.
