what is the weight limit for this rack system
165 lb weight limit for these.
Althouh probably not encouraged by Thule, I have seen vehicles utilizing 3 and even 4 sets of these gutter towers and crossrails. Assuming your gutters are up to the task I would think the weight limit for 3 sets of towers would be 247.5 and 4 sets of towers to be 330. Of course the load would need to be evenly distributed. Just a thought.
