Features to Know About

Rugged Design for Year-Round Adventures

Thule Force 3 on small carThule Force 3 diamond-plated AeroSkin surface

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 your car gets old fast. The Thule 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.

Pack Tall, Pack Smart

Thule Force 3 fits the whole family

A lot of taller gear just won't fit into a lower profile box. The Thule Force 3 gives you the extra height you need for bulky camping gear, oversized duffel bags, and other road trip essentials. No more cramming or rearranging all the gear in your trunk or back seat - just load up the box and hit the road.

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

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 Unloading

The Force 3 makes unloading easier - and safer - especially if you have to pull to the side of the road or park in a tight garage. The lid opens from either side, so you can grab your gear without stepping into traffic.

Keeping Thieves at Bay

Thule Force 3 locksThule Force 3 red indicator

When you're on the road, keeping your gear secure is a top priority - stopping for gas, grabbing a bite to eat, or leaving your car overnight. The Force 3 has built-in locks on both sides that keep the lid tightly shut. A red indicator shows when it's fully locked, and the key won't come out until everything is secure. No second-guessing, no accidental openings - just lock it and go.
