Why Choose the L Size?
The Force 3 L is a versatile choice for families and active travelers who need more storage without moving to one of the largest cargo box sizes. Its 16-cubic-foot interior provides useful room for road trips, camping weekends, ski vacations and everyday transportation.
The 76.8-inch length can accommodate skis up to 175 cm, while the 33.3-inch width provides additional room for luggage and general cargo. Always confirm the available roof space, crossbar placement and rear-hatch clearance on your vehicle.
Versatile Capacity for Every Season
The Force 3 L can accommodate up to 5–7 pairs of skis or 3–5 snowboards. Outside of winter, its spacious interior is ideal for duffel bags, tents, sleeping bags, strollers and other bulky travel equipment.
The cargo box has a maximum load capacity of 165 lbs. Your actual allowable cargo weight is determined by the lowest-rated component in the system, including the vehicle roof, crossbars, mounting system and cargo box.
Fast and Secure PowerClick Installation
Thule’s PowerClick quick-mount system makes installing the Force 3 straightforward and intuitive. The tool-free mounting hardware tightens around compatible crossbars from inside the cargo box.
An integrated torque indicator produces an audible click when each mounting point has been tightened correctly, helping remove the guesswork from installation.
Convenient Access from Either Side
DualSide opening lets you load and unload the cargo box from either the driver or passenger side of the vehicle. This flexibility is especially useful in garages, parking lots and campsites where access may be limited on one side.
The sculpted lid creates a natural grip for easier opening and closing without a bulky external handle.
SlideLock Security
The integrated SlideLock system separates the opening and locking functions. It automatically locks the lid and indicates when the cargo box has been closed correctly, helping ensure your equipment is secure before you drive away.
Built and Tested for the Road
The durable AeroSkin surface is designed to handle the demands of regular use while maintaining a clean black matte appearance. Its streamlined profile complements modern vehicles and helps limit unnecessary wind resistance and road noise.
Thule tests its rooftop cargo boxes at the Thule Test Center and in real-world road conditions. The Force 3 has undergone extensive safety and durability testing to help protect your cargo mile after mile.
