Expand Your Vehicle’s Potential – Rugged and Versatile Design
The Thule Force 3 range balances strength, style and everyday practicality. Designed for active families and outdoor use, it provides the extra space you need for weekend breaks and longer journeys alike. Sizes run from the compact S through the Thule Force 3 M Roof Box to the Thule Force 3 L Roof Box, so there is a fit for most vehicles and most loads. The durable AeroSkin surface withstands the elements while keeping the sleek, modern profile that makes it dependable year-round.
Practical Integration With Modern Vehicles
The Thule Force 3 Roof Box adds storage capacity while working with the aerodynamics of modern vehicles rather than against them. Its streamlined profile reduces air resistance and wind noise, which helps limit the effect on fuel consumption. The AeroSkin material resists wear and weathering, making the box a dependable long-term addition to the car.
Designed For Convenience
With the Thule Force 3, accessing your gear is easy and secure. The cargo box is equipped with the PowerClick quick-mount system, which ensures a fast and reliable fit. The integrated torque indicator clicks to confirm when it’s securely attached. The SlideLock system offers separate locking and opening functions, automatically locking the lid and indicating when it’s properly closed. DualSide opening allows for quick access from either side of the vehicle, simplifying the loading and unloading process.
Safety and Durability
Thule puts the Thule Force 3 Roof Box through extensive road and lab testing at the Thule Test Centre to surpass industry safety standards and protect your cargo in every condition. Additional features such as the integrated box light and easy-to-use pull strap make it a rugged, family-friendly choice that blends practicality with peace of mind.
