KAMEI Corvara S 475 carbon grey roof box no. KM538 (0 81538 21)

RRP: 542.95

A large capacity medium-width box that should provide roof bar space for two bike carriers.

KAMEI's Corvara S range is as good as it gets for materials and build quality, with sophisticated and enduring good looks. This box comes with DuoLift opening on gas-assisted struts, "Just pull shut to lock" central locking, and the ClickFix box to bars fitting system, the lowest-profile and fastest fitting system on the market for T-track aluminium roof bars.

Only fits T-track aluminium roof bars - won't fit solid/square roof bars.

KAMEI's Corvara S boxes are as well engineered as any boxes on the market. They look distinguished on any car, have a superb 'Just pull shut to lock' central locking system that makes them very easy to use (all KAMEI boxes have an easy closing feature of one sort or another), and have gas-assisted struts that allow for a smooth opening and closing motion that just isn't possible with other systems. And they also have KAMEI's ultra-low-profile ClickFix system, "the fastest in the world", for fixing the box to all brands of slotted aluminium bars, including BMW's. Note that the Corvara S boxes can't be fitted to steel bars.

Customers buy the KAMEI Corvara S 475 because it looks so good and is so well made, has a large capacity, and should leave roof bar space to carry two bike carriers. It is for sure the best quality medium-width long box on the market. Because it's a particularly long box, it's likely to hang out over the windscreen, but we say "So what? You won't see it unless you lean forwards and then look upwards".

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!

KAMEI 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.

The ClickFix system is claimed to be "the world's fastest roof box mounting system". Certainly we can't see how it could be any faster. Place the ClickFix over the T-track slot in the aluminium bar and push the clamp down; done! The ClickFix automatically adjusts to all T-track profiles, even the BMW ones that usually require special adapters. Note that ClickFix can only be used in Thule's Evo WingBar if the rubber strips on both sides of the T-track are not fitted - but of course these rubber strips can be fitted on either side of the box if needed. In this respect it is the same as the previous Thule WingBar, and it really is a very minor issue - there are even Thule accessories that can't be fitted to their Evo WingBar "with the rubbers in".

Some other features:

  • Externally, 230cm long x 75cm wide x 41cm high
  • Internally, 218cm x 65cm x 37cm
  • The empty box weighs 19kg, 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.
  • The whole range is TÜV and GS (security) tested and approved.
  • Corvara S boxes open from either the left or the right hand side, making them very easy to fix to roof bars (no stretching into the box is needed), as well as providing full choice about positioning (left, right or centre).
  • The patented DuoLift opening system includes gas struts which allow for smooth opening and closing, as well as a very wide opening (to 35cm) for easy loading and unloading.
  • 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 3 combined locks/hinges are at just the right places for optimum security.

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 Standard two to four day service is £6.50 (£11.50 for orders including a roof box) and our charge for Express Delivery (one or two days) is £9.50 (£14.50 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 (courier, usually Express Delivery).

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 Express Delivery need to be received by 4pm.

When will my order arrive?
There are no deliveries on Saturdays, Sundays or Bank Holidays, except for postable items where Royal Mail has a Saturday delivery. Express Delivery orders placed on a Friday should be delivered on the Monday or Tuesday, Express Delivery orders placed on a Saturday should be delivered on the Tuesday or Wednesday.

What about Next Working Day delivery? 
We have offered a reliable Next Working Day service for well over 20 years but, due to the pressure on the couriers caused by the coronavirus crisis and the huge increase in online shopping, we can no longer be confident about the delivery date, which is why we now call the service ‘Express Delivery’.  Many Express Delivery orders will arrive on the next working day, but some will arrive on the second working day, or be split between these two days. So-called “split deliveries” happen when the couriers do not have enough trailer space for everything that should be moved around the UK, so they will load what they can, and leave the rest for the next trailer.

Is my delivery day guaranteed?
No retailer or courier company can ever "guarantee" a Next Working Day delivery. As well as split deliveries, 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.

Do I need to be at home?
We are very flexible with our deliveries and will aim to deliver to an address which suits you – this does not need to be your home address. 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.
