‘Through bars’ have the metal bar itself extending past the mounting leg where it connects to the vehicle. These are generally more practical and give you physically more bar space. We recommend this style of roof rack for people who want to make the most of their roof space. This is also our recommendation for people who plan on carrying kayaks, SUPs, and bike carriers as the overhang can assist with side mounting. If you plan on mounting an awning to your bars, the 'Through' option is definitely the style we would recommend as the leg on the 'Flush bar' can impede you from attaching the awning bracket.
‘Flush bars’ have the bar finishing at or into the leg. This sleek design provides a sportier and neater look. Due to the style of legs that is used these racks can sometimes sit slightly lower on your vehicle. This style offers less mounting space due to the integrated leg system that takes up 10-15cm of bar space. There is also a reduced chance of a flush bar fitting your next vehicle.
Although through bars offer more space for mounting, they generally do not offer a larger weight capacity. With that in mind, thanks to the extra room provided by the 'Through bar' you are able to carry a wider range of items as you are less restricted by the length of the bars.
Please take into consideration the type and size of items you will be carrying when purchasing your roof racks.
