KAMEI Fosco 540 gloss black roof box no. KM540 (0 81540 21)

RRP: £635.00
Code: KM540

KAMEI's new Fosco 540 is an adventurous design - it's designed for efficiency (reduced drag, maximum real-world load carrying capacity) which really means that it's designed to complement the latest in car design concepts. It deserves to be a winner!

Please note that it only fits to T-track aluminium roof bars; it doesn't fit to steel roof bars without additional parts.

IF Design Award winner 2019!

What's so special about the KAMEI Fosco?

Compared to the standard shape of roof box, some might think the new Fosco looks like a fish out of water when first removed from its carton, but put it on a modern car roof and it's obvious that it's now back in its element. Stand to one side and you'll see that the long raking nose follows the line of the car windscreen, and the Fosco's gently falling lid-line follows the car's gently falling roof-line. And now that the whole box is correctly poised, its gently falling lid to base line draws the eye forwards to the front of the box, and echoes the same falling styling line (above the door handles) that you'll see on so many of the latest cars. The KAMEI designers have done something really smart with this box design.

The Fosco's styling follows the 'teardrop' contours of the modern car, reckoned to be the most aerodynamic shape available - wider and higher at the front than at the back, to minimise drag and to maximise fuel efficiency.

We are really interested to note, as roof box nerds, that the designers have taken the stiffening ribs out of the base and put them instead into the box sides - this might not make much difference to the nominal capacity but, together with the use of the lowest possible profile ClickFix roof bar fittings, this near flat base gives a lot more real world load carrying space than would otherwise be the case.

So now you only need to add KAMEI's exceptional build quality, and features including DuoLift opening (opening the box from either side) and Stabilus gas-strut assisted lid openers (extra wide, extra smooth) and a 'Just pull to shut' lid closing system, and this Fosco is a box that ought to be on your short list if it's within your price range and you are looking for a large, spacious box.

More information on core features

ClickFix: The ClickFix system is claimed to be "the world's fastest roof box mounting system". Certainly we can't see how it could possibly be any faster. Place the ClickFix above the aluminium roof bar T-track slot and push down the handle. Done - it automatically adjusts to all T-track profiles, even to BMW profiles that usually require special adapters.

Just pull to shut central locking: KAMEI's central locking systems have the benefits of central locking without the potential drawbacks. Turn the key and the lid opens wide on its gas struts, but to close it you just pull the lid until it clicks shut - no need to hold the front and back shut while simultaneously turning the key. And you can’t lock the keys in the box inadvertently because the keys can’t be withdrawn from the lock until the box is properly shut. This is clever engineering.

Duolift with gas struts: This Duolift box opens from either the left or the right hand side, making it very easy to fix to roof bars (no need to stretch across the box), as well as providing full choice about where you position it, depending e.g. on what else you are carrying on the roof, and which side to load and unload. The DuoLift system includes patented gas struts for wide and easy opening and closing. There are wel-integrated handles on each side of the lid to make opening and closing even easier.

Some other features:

  • Externally 216cm x 94cm x 44cm
  • Internally 204cm x 80cm (front) / 74cm (back) x 39cm - it's a very large box that makes optimal use of its 540 litre capacity
  • The empty box weighs 22kg, and it's certified to carry a maximum load of 75kg. You should note your vehicle's maximum roof loading limit, and the weight of the roof bars and roof box, before working out what maximum weight you should carry.
  • All KAMEI boxes are TÜV and GS (security) tested and approved.
  • The ClickFix box to bar fittings slide at all four fitting points so there’s never a need to drill new holes if the distance between your roof bars is non standard.
  • The ClickFix can't be used with steel roof bars. If you want to fit a Fosco to steel roof bars, you'd need to replace the ClickFix with the Comfort Sliding Fitting system; this would be an unusual request, so please e-mail [email protected] for more information.
  • The 3 combined locks/hinges are at just the right places for optimum security.


There's a general consensus that KAMEI, based in Wolfsburg in Germany, makes the best quality boxes on the market. Don't just take our word for it! They're a specialist box manufacturer, Quality Assured to ISO 9001, represented in over 40 countries, with numerous Best Buy awards over the years, including the last 6 consecutive Auto Express "Best Buy" awards!

With their innovative and intelligent designs, top quality materials and engineering, and outstanding build quality, it's no surprise that KAMEI are Original Equipment box suppliers to several major manufacturers, including Audi, Mercedes-Benz and VW. And their boxes have the longest guarantee of any manufacturer in the car rack systems sector - 6 years!

In summary:

KAMEI's whole heritage is in forward thinking automotive design. The Fosco is an exciting addition to their line up and deserves to be a great success.

Do you need roof bars as well? If so, check out our amazing box and bars package deal which provides everything you need, including this box, locking roof bars, and a roof box storage device, all for a fixed price! Click here for more details.

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. (Note that only one box hoist or one set of straps will be included per roof box ordered!)

If you're ordering this roof box as part of a Package Deal, you will select your free gift once you've chosen your roof bars.

Very few customers know much about the roof box market before they visit our site. We have a lot of information about the things to think about before buying, and the “real world usefulness" of various roof box features, but you’ll be buying sight unseen, and you probably won’t have used a roof box before, so there is inevitably some luck in getting a box that you’ll be happy with.

We want to remove the risks of buying these large and often expensive items, perhaps from brands which almost every other roof box retailer doesn’t stock, and so we have a unique “90 day Exchange Scheme” for roof boxes.

This allows you to use a roof box and, with the benefit of experience, to exchange it for a new one within 90 days of invoice date. Most exchanges are from a shorter box to a longer one, or from a wider box to a narrower one.

These are the rules of the Exchange Scheme:

  • You are allowed one exchange only.
  • The original box must be in "as new" condition, subject only to fair wear and tear.
  • The replacement box must be a different model.
  • The replacement box must not be part of a package deal or be from our Bargains section.
  • Roof bars are never part of the Exchange Scheme.

This is how the exchange scheme works:

  • We charge in full for the replacement box, including the appropriate carriage charge and a charge for any packaging needed for the return of the original.
  • We arrange the collection and pay the return carriage costs.
  • When the original box arrives back here we refund you for the invoice value of the original box, but you won't get back more than the invoice value of the replacement box. In other words, if the replacement is cheaper than the original we won't be giving you "extra cash back".

Please note: we can only collect items from mainland UK.

Delivery charges and arrangements:

We charge a contribution towards delivery costs, depending on what you order, where you live, and how quickly you want the goods.

For most UK addresses, the charge for our two to three day service is £5.50 (£9.50 for orders including a roof box) and our charge for Next Working Day deliveries is £8.50 (£12.50 for orders involving a roof box). AutoSock, shoe chains, RUD i-Sock, and small spare parts, are charged £3.95 (Royal Mail Tracked), £4.95 (Royal Mail Express Tracked) or £5.95 (express courier, usually Next Working Day).

There are different charges for any delivery including a sea crossing, and deliveries to Skye - we will contact you with a quote on receipt of order.

Orders for Next Working Day delivery need to be received by 4.00pm.

There are no deliveries on Saturdays, Sundays or Bank Holidays, except for postable items where Royal Mail has a Saturday delivery. Next Working Day orders placed on a Friday will be delivered on the Monday, Next Working Day orders placed on a Saturday will be delivered on the Tuesday.

We are very flexible with our deliveries and will aim to deliver on a day and at an address which suits you. Goods can usually be left without signature - we prefer this with roof boxes. There's a "Special Delivery Instructions" box in the checkout area where we'll ask you to choose a typical instruction and then amend it to suit your particular requirements.

No retailer or courier company can ever "guarantee" a Next Working Day delivery. All courier companies occasionally have the same transport problems as can happen to everyone else, including snow blocked roads, closed roads, traffic jams, mechanical breakdown, an inability to find the delivery address, or to gain access to it if, for example, it's in a block of flats. We work with some of the best couriers in the business, and overall they provide an outstanding service.
