Popular roof box for small-medium sized cars
Robust and stylish roof boxes for everyday use on the road. The tough Aeroskin textured finish offers aesthetics to compliment any modern vehicle, and the aerodynamic design helps reduce noise whilst travelling. Featuring dual-sided opening for ease and convenience of accessing your roof box from either side of the vehicle, so it doesn't matter if you are parked against a wall. Easily open and lock the Force 3 Medium with the SlideLock mechanism. This ensures the lid is securely closed with a visual indicator before you lock the box.
Fitting the Force 3 roof box to your vehicle is made easy with the Powerclick Mounting Clamps. These torque-limited fittings will click once the correct mounting pressure has been applied, and are compatible with a range of popular roof bars including SquareBar, WingBar Evo and WingBar Edge systems. The Force 3 features runners for the mounts to clip into, allowing you to position the clamps to suit various distances between your roof bars.
The Force 3 Medium size is great for small to medium sized vehicles such as small hatchbacks, estate cars and mini SUVs, but can equally be used on larger vehicles too. Offering 400L of load space and 75kg of load capacity, with internal load dimensions of 167 x 69 x 38cm.

Boot Hatch Clearance
When mounted on your vehicle’s roof, a roof box may come into contact with your rear boot hatch. To determine which roof boxes fit your vehicle without contacting your hatch, measure the front clearance. This is the distance from your vehicle's front roof rack crossbar to the point where the roof meets the hatch (see image below).

If your vehicle measures greater than 1149 mm, the Force 3 M roof box will fit your vehicle without contacting your hatch.
Note: Some roof racks that use flush rail, raised rail or fix point fittings feature adjustable position crossbars. Moving the crossbars forward on the vehicle will increase the number of roof box models that fit without contacting the boot. If you're unsure whether your vehicle's crossbars can be re-positioned, see your vehicle or roof rack manufacturer for assistance.
