I have owned this base support rack system for a long time and loved it's versatility and simplicity. Available with locks at each foot that work with a single key, you have the satisfaction of knowing your roof rack is secure.
The Thule 300 system works with cars equipped with rain gutters and is one of the most universal roof rack systems available. The load bars are also available in different lengths to accommodate the width of your particular vehicle's roof.
Thule manufactures a large number of carriers that can be attached to the LB50 load bars including bike trays, ski racks, boat carriers etc.

If your car has rain gutters, and you are looking for a good, sturdy, versatile base support system, look no further. Thule 300 is the best!
