Stepping into the world of roof bars can be both daunting and costly, but the UKB4C Locking Car Roof Bars prove otherwise. Offering a fantastic blend of utility, affordability, and robust design, these bars truly impress. Having thoroughly tested them, their performance exceeded expectations, notably with their compatibility and affordability compared to more renowned brands.

Design and Build Quality

Constructed from sturdy, lightweight aluminium, these bars are impressively resilient. Their aerodynamic shape not only adds to the aesthetics but also enhances their functionality. The bars are TUV/GS tested and can comfortably hold up to 75 kilograms. Hence, it is clear that UKB4C hasn't skimped on either the quality or the capabilities of these bars.


  • Lightweight yet robust: The aluminium build ensures a robust structure without adding unnecessary weight.
  • Capacity: Tested to withstand a weight of 75 kilograms, which is more than sufficient for most needs.
  • Aerodynamic Design: The streamlined design helps to reduce wind resistance and noise.

Ease of Use

Designed with the user in mind, these roof bars are equipped with a unique locking mechanism. This might require a bit of practice to understand the system fully. Unlocking before attaching and ensuring that the key is either in the lock or the lock is unlocked before putting it back on are vital steps to ensure secure placement and prevent any damage. Once these steps are understood, installation becomes a breeze.

However, one small hiccup comes in the form of the provided instructions. They could have been clearer, especially regarding how to tighten the bars. But once past this hurdle, both mounting and dismounting the bars are straightforward.


One standout feature of these roof bars is their universal compatibility. They fit perfectly on a range of vehicles, including the 2022 Kia Exceed and the 2019 E-class estate. Furthermore, these bars are particularly suitable for vehicles with low-profile roof rails, a common feature on most Kia models.

Value for Money

In a market where similar products from Roof Box Company and Halfords command higher prices, these bars offer excellent value. Not only are they affordable, but they also match the weight limit offered by more costly alternatives like the Halfords ones priced at £90.

However, one minor shortcoming is the plastic caps on the security locks. They can be easily removed by hand, but this doesn't overshadow the overall performance and value these bars offer, especially considering that it is not advisable to store valuable items in a roof box.


The UKB4C Car Roof Bars have been tried and tested with a large roof box, and the verdict is overwhelmingly positive. They provide a secure fit, easy setup, and excellent value for money. In the grand scheme of things, the minor drawbacks are largely outweighed by the benefits. If you're in the market for roof bars, these are a fantastic choice that won't break the bank.


  • User-Friendly: Easy to install and remove once you understand the locking mechanism.
  • Universal Compatibility: Compatible with a variety of vehicles, making them versatile.
  • Affordable: Significantly cheaper than competitors but matches their performance.
  • High Value for Money: These roof bars deliver more than you'd expect at this price point.
