Features to know about

Sized Just Right

Thule Force 3 fits the whole familyThule Force 3 loaded with gear

You can fit more than you'd think in this compact box - duffel bags, luggage, camping gear, and more. It's a solid match for weekend trips, short getaways, or whenever the trunks running out of room. Unlike larger boxes that eat up most of your crossbar space, this one leaves room to spare, so you can still mount a bike rack, ski carrier, or other gear alongside it - especially if you have a small vehicle or flush crossbars with no overhang. It's also light enough to lift on your own and small enough to stash on a garage shelf when it's not in use.

Rugged Design for Year-Round Adventures

Some roof boxes are designed to turn heads with sleek angles and glossy finishes, but those don't always hold up to real-world use. Hail, road debris, and low-hanging branches leave their mark, and constantly taking the box on and off gets old fast. The Force 3 gives you the best of both worlds - a rugged, diamond-plated AeroSkin surface that won't highlight every scratch. Leave it on year-round and stay ready for your next adventure.

No Over-Torquing, No Crossbar Damage

Thule Force 3 torque knobs and crossbar clamps

Installing the box couldn't be easier. No wrenches, no guesswork - just set it on your crossbars, insert the clamps, and tighten them by hand. When they're fully secured, you'll hear a click, so you know they're locked in place.

Secure Tie-Down Points

Thule Force 3 internal tie-downs

Inside, built-in anchor points give you a secure spot to attach the three included tie-down straps, keeping your gear from shifting on bumpy roads. No more unpacking a jumbled mess when you arrive - just grab your gear and go.

Dual-Side Access for Safer, Smarter Loading

The Force 3 makes unloading easier - and safer - especially if you have to pull to the side of the road or get stuck in a crowded parking garage. The lid opens from either side, so you can grab your gear without stepping into traffic. And when you stop for a bite, locks on both sides keep everything secure, so your gear stays right where you left it.

  • Where is the Thule Force 3 L Sport Rooftop Cargo Box Made?
    Hey Pat, thanks for reaching out! Even though the Thule brand has its roots in Sweden, the Thule Force 3 L Sport Rooftop Cargo Box # TH77SA is manufacture red here in the US so it sounds like it's right up your alley. Let me know if you have any other questions!

  • What to Think About When Purchasing a Roof Cargo Box for a New Vehicle
    Hey Renzo, thanks for reaching out! Choosing the correct cargo box depends on the size of your vehicle and what kind of space you have to work with. For example, the Thule Force 3 L # TH77SA is 75-1/8" long x 24-3/4" wide x 16-3/4" tall while the Thule Force 3 XXL # TH27SA is 91-1/2" long x 35-1/8" wide x 18" tall so it gives you more cargo space, but it also is more likely to interfere with a rear hatch if that's something you all have. If you can let me know what vehicle you all purchased...

  • Recommended Roof Rack and Cargo Box for a 2023 Honda Accord Sedan
    Yes, it will Zach! To install the Thule Force 3 L Sport Rooftop Cargo Box item # TH77SA on your 2023 Honda Accord sedan, I recommend the Thule WingBar Edge Roof Rack item # TH75NG. This aero bar roof rack is a flush mount style which means the crossbars will not extend out past the mounting legs. This is the perfect type of roof rack to use with cargo boxes like the Thule Force 3 L Sport item # TH77SA. The clamps included with the cargo basket will easily attach to the crossbars included...

  • How Easy is it to Open the Thule Force 3 L Sport Rooftop Cargo Box TH77SA?
    Hey Denny! So long as you do not overload the Thule Force 3 L Sport Rooftop Cargo Box item # TH77SA it's pretty easy to open and close. It has dual-sided access, which means you can open it on both sides of your vehicle for added convenience. The latch can be opened using only a finger and thumb. You're going to want to be careful opening it in the wind though. What kind of vehicle are you looking to mount this cargo box on?
