This is a very nice looking box indeed, made of full grade ABS plastic and - thanks to its integral steel reinforcing sections - TÜV approved for loads to 75kg. We reckon the Spirits are by some way the best boxes that Thule have ever made.

• Dual Side opening so you can choose to use it on either side of the vehicle. You'll find it easier to load and unload if it's fitted towards the edge of the vehicle; you'll always be stretching if you fit it centrally. There is a 'One Key System' compatible central locking system on each side of the box.
• Thule's new "diffuser technology" - the reinforcing ribs are longitudinal, suggesting that this box will be almost silent in use. We'll let you know if we find that this makes an appreciable difference. The reality is that all boxes generate additional drag and wind noise; quality boxes are designed so that you probably won't notice a noise unless you decide to drive with the sun roof open.
• "Power-Grip" - you just turn each wheel to draw the fitting claws around the roof bars, making this box easy to fit to all known roof bars. Thule's new Power-Grip gets around any need to use adapters to fit boxes to unusual shaped bars, although the downside is that these fittings take up a lot of space in the box. (Our general advice on packing roof boxes is that bags / grips are easier than suit cases.)
• If you're using aerobars we recommend that you remove these bulky Power-Grip fittings (remove 1 screw and they lift out very easily) and use the T-track aerobar adapters; these provide an invisible box to bar fitting as well as allowing you to make full use of the box capacity. Check the pop-up links to work out which adapters to buy.
• Box weight 26kg. Before loading the box, check your vehicle's maximum permitted loading limit, taking into account the weight of the roof bars, the weight of the box, and the weight of the contents.

This season we are offering a free roof box hoist to give you a superb deal. Boxes are bulky items so the ideal place to store them is above your car in the garage, or perhaps in a shed. Many people will leave the box attached to the bars, and also use the box for storage.

If you don't need a box hoist, our alternative gift is a set of 3 Fasty straps - 0.5m, 1.5m and 3.0m. Although of much less financial value they will be useful for 1,001 things, time and again. To order the 3 straps, 'untick' the Free box hoist "Order Item?" tick box by clicking in the box, and then tick the Free straps one instead. Please note that these free items are included at 10p for our record keeping purposes only, and that only one box hoist or one set of straps will be included per roof box order.
