Types of Roof Boxes

Consider your needs before choosing a roof box. Here are some common types:

Small - Under 400L

Perfect for hatchbacks and smaller vehicles. Examples include:

Half-Width Roof Boxes

Ideal for carrying bikes, water sports equipment, or roof tents like the Thule Foothill Roof Tent.

Ski Boxes

Designed to securely carry skis and snowboards. Explore options like:

Large - Over 500L

Ideal for family holidays, camping, fishing trips, and large luggage.

2. Weight Capacity

Ensure the roof box can handle the load you plan to carry. Entry-level boxes carry up to 50kg, such as the Thule Ocean 80, 100, 200 & 600.

Mid-range and premium boxes, such as the Thule Force, Motion, and Vector Ranges, carry up to 75kg.

3. Material & Durability

Look for roof boxes made from durable, weather-resistant materials like ABS plastic or fiberglass for maximum protection against the elements. Thule products are tested to meet high standards - Explore Thule's Test Center.

4. Mounting System

Roof boxes typically feature one of four main mounting systems: U-Bolt, Quick Clamp, T-Track, and Powerclick. Learn more about Roof Box Mounting Systems.

5. Security Features

Choose a roof box with secure locking mechanisms to protect your gear. Many Thule boxes feature central locking systems that secure all attachment points at once, including the Thule Force, Motion, and Vector ranges.

6. Aerodynamics & Noise

Opt for an aerodynamic design to reduce wind resistance and noise, improving fuel efficiency and providing a quieter ride.

7. Storage & Waterproofing

Ensure that your roof box has effective seals to keep your gear dry and is easy to store when not in use. For better storage, consider using a Multilift or a Box Cover to protect your box.

8. Brand Reputation & Reviews

Research customer reviews and choose reputable brands for more reliable products.

9. Warranty & Customer Support

Look for roof boxes with a solid warranty and strong customer support. Thule offers a 5-year warranty on all their boxes
