KAMEI 510 glossy black roof box no. KM440 (81440)

A new box from KAMEI in glossy black - really smart!

KAMEI 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 six 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 they are Original Equipment box suppliers to several major manufacturers, including Audi, Mercedes-Benz and VW. And KAMEI boxes have the longest guarantee of any manufacturer in the car rack systems sector - 6 years!

It includes KAMEI's ingenious central locking system - all the benefits of central locking without the potential drawbacks:

The box is unlocked with a quarter key turn, but locked again just by pulling the box shut. Big deal? Actually, yes. All other central locking systems have a big drawback when it comes to closing the box, because you need to turn the key in the lock at the same time as holding down both the front and the rear of the box – which is a three handed operation if the lid is being held up by bulky gear, or if the base is sagging due to incorrect loading or weakness.

The KAMEI system has three catches and three hinges, for extra security. And you can’t take the key out of the lock until the box is properly shut. It's a really neat system.

• Made from top quality 'DUROKAM', an ABS plastic developed by KAMEI to optimise weight, stability and impact resistance.
• Wind tunnel development as well as TÜV and GS (security) testing and approval.
• This Duolift box opens from either the left or the right hand side, making it very easy to fix to roof bars (no stretching into the box is needed), as well as providing full choice about where you position it, depending e.g. on what else you are carrying on the roof.
• The DuoLift system includes patented gas struts for wide and easy opening and closing.
• Sliding box to bar fittings so there’s never a need to drill new holes if the distance between your roof bars is non standard.
• This box comes with T-track adapters which slide into the slots in the top of aluminium roof bars (including all the aluminium bars we sell), and also with U-bolts (M8 thread) which fit around bars up to 83mm wide x 32mm deep. It always makes sense to use T-track adapters with aluminium roof bars, because these allow you to position the box anywhere on the full length of the bars, they produce a much smarter look (no bits of metal visible below the roof bar) and it's a more aerodynamic fitting system. T-track adapters also allow you to push the box further back or forward than is possible with U-bolts - which can be important if there's a potential clash with a fully opened tailgate. And T-track adapters also provide more flexibility in roof box positioning than claw style fittings (this is the type which grabs around the roof bars and is tightened with a turning wheel inside the box) - this is because claw fittings should not be used in the area of the roof bar feet (these fittings will touch the feet before they are tight enough on the bars) so you may not be able to position the box just where you want it. Claw fittings also limit front to back positioning. So now you know why KAMEI includes standard T-track adapters (which are an extra cost for all other brands of roof box) and does not use claw style fittings.
• If you have BMW roof bars, note that these have unusually wide T-track slots, and will require additional adapters - see part KM52004 in the list below.
• 6 year guarantee.
• Holds up to 6 sets of skis (max length 185cm).
• Weight 18kg empty, maximum load 75kg, gross loading limit 93kg.

Bulky Items

Long Wide roof boxes and some other items that are either very large or very heavy (e.g. roof tents) are, for safer and more careful handling, best carried by two people.

Bulky Items are delivered via the ArrowXL 2-person delivery service. ArrowXL will contact you to arrange a delivery date, using their online booking service. You should allow up to 3 working days after order for delivery, but note that it's our aim that all boxes ordered during the weekend (if in stock) will be despatched on the Monday, for delivery from Wednesday onwards. Saturday and evening delivery slots are often available. All other products that are part of the same order will usually also be delivered by ArrowXL, at the same time as the Bulky Item.

Please note that deliveries from ArrowXL need to be signed for, e.g. by a neighbour if you are not at home, or you can have the goods delivered to a different address.

There is a £25 surcharge for Bulky Item deliveries to the Grampian area, Scottish Highlands, any GB delivery including a sea crossing, and Northern Ireland. There is a £50 surcharge for Bulky Item deliveries to the Isle of Man, the Channel Islands and the Republic of Ireland. Deliveries to all these places will take longer than normal, sometimes much longer - delivery timings are indicated in the Shopping Basket.

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 (before 1pm) should be delivered on the Monday or Tuesday, Express Delivery orders placed on a Saturday or Sunday should be delivered on the Tuesday or Wednesday. The arrangements for Bulky Items are different and are shown above.

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’. Most Express delivery orders will arrive on the next or second working day, but some will arrive on the second or third working day, or be split between these 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. Except for Bulky Items, 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.

Payment options:

We take the following cards, and also PayPal. Please note that the entry on your card statement will be from "The Roof Box Company".
