Package deal: Atera Casar M AR2291 roof box, textured lava grey, and bars

This superb box and bars package deal provides everything you need for a fixed price, including locking roof bars. All you need to do is to click on "Select box" and we'll then show you which roof bars are available. You'll pay more for aluminium than steel, and you'll pay more for Atera, Thule, or Yakima, but the savings on buying the components individually are huge. We're confident that you won't find such good value anywhere else.

The Atera Casar is a top end roof box, with a purposeful, fine-looking lid design that maximises the internal space while still providing the rigidity and stability required. The roof box base includes recesses which bring the whole box closer to the car roof; these recesses are long enough to accommodate widely-spaced roof bars or prominent rear tailgate spoilers; in other words, we expect the Casar to be able to be fitted to all cars.

It opens on the right-hand side, and uses Hapro's Master-Fit claw-style box to bar fittings - these are very are easy to use, fit to all the bars we sell except for Thule ProBars (not available in package deals), and don't take up much room in the box.

Other features:

• This box has a textured lava grey (a very dark grey, near black) lid on a matt-black base. The textured finish has anti-scratch properties.
• Externally, 177cm x 77cm x 42cm - plenty of space for one bike carrier, even on the shortest 'through' bars we sell.
• The empty box weighs 14.5kg, 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.
• Master-Fit box to bar fittings are suitable for almost all roof bars, including all the bars we sell except Thule ProBars. They'll fit 95mm wide x 38mm deep oval or wing-shaped bars, or 95mm x 28mm rectangular bars. Note that Master-Fit include a locking device so they can't be loosened accidentally.
• It uses central locking - you can't remove the key from the lock unless the box is properly closed
• Internal luggage straps are included to help secure your gear inside the box; they should be used, especially if carrying narrow and heavy items such as skis.
• Atera Casar boxes have been thoroughly tested by the German TÜV to the latest standards, including "City Crash testing".
• 5 year guarantee

Atera is the leading German car rack systems brand, although they have their boxes made for them by Hapro in Holland. Atera's commitment to engineering excellence and quality is demonstrated by the fact that the majority of their business is with the Original Equipment market, i.e. direct to the car manufacturers, where major customers include Audi, BMW, Daewoo, Chrysler, Fiat, Honda, Mitsubishi, Mercedes, Opel, Subaru, Suzuki, Vauxhall and Volkswagen.

Summary: A top-notch box with superb build quality; it's a pleasure to use. The materials quality is up there with the KAMEI Fosco series (and is much better than the Thule Motion XT series); we're pleased to give it an overall five star rating.

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, only paying a contribution to our carriage costs. 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. Not just an alternative colour.
• 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 carriage charges, and a charge for any packaging needed for the return of the original.
• If you want us to collect the original box, there will be a £50 carriage charge (please note that regional surcharges may apply).
• We arrange the collection, if requested.
• 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".

If you want to exchange a box that was purchased as part of a package deal, the scheme works in exactly the same way. Please note that the roof bars in package deals will be invoiced at the full “Our Price” that was advertised at the time of order, with the box representing the difference between the package deal price and the roof bars. Package deal roof boxes are often invoiced at a very substantial discount to the cost of buying that box on its own, so it’s likely that you’ll need to pay a bit extra if you want to exchange for a box that is normally the same price as the one you’re trading in.

Please note: we can only collect roof boxes from mainland UK.

Delivery FAQs

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 Very Heavy 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. 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.
