KAMEI Corvara 310 silver roof box right side...

The superb Corvara range of boxes was launched earlier this year; it's KAMEI's 'flagship' range, and incorporates the best of their engineering innovations, including their new low profile "push-push" quick fitting system.

The central locking system has the benefits of central locking without the potential drawbacks. Turn the key and the lid rises 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 And you can’t lock the keys in the box inadvertently because the keys can’t be withdrawn from the lock until the box is properly shut. That's clever engineering...

The box to bars fitting system is extra low profile to maximise the useable space in the box. Push all four U bolts into the guides below the box - they're held in place with special grippers - and then, placing one hand into the box, push the spring loaded tensioning arm up and down a few times - "push, push, push" - to tighten the box onto the bars. It's a one finger operation, strain free!

Some other features:

• Corvaras are made from top quality 'DUROKAM', an ABS plastic developed by KAMEI to optimise weight, stability and impact resistance.
• The shape was refined after wind tunnel testing, and the whole range is TÜV and GS (security) tested and approval.
• This box opens from the right hand side.
• It uses Stabilus gas struts for wide and easy opening and closing.
• There are sliding box to bar fittings 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 locking mechanism uses metal components throughout, including the catches in the lid; there are 3 locks and 3 hinges.
• This box comes with fittings to accommodate roof bars up to 44mm wide. If you'll be using aluminium aerobars, or your roof bars are wider than 44mm, you'll also need to purchase one of the adapter sets listed below.
• 6 year guarantee.
• Weight 14kg empty, maximum load 50kg, gross loading limit 64kg.

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, tick the Alternative free gift box below. Please note that only one box hoist or one set of straps will be included per roof box ordered.

The lids of the silver KAMEI Delphins and Corvaras are now made of a "scratch-resistant" plastic, a very technical finish which is increasingly being used for body parts by top end car manufacturers. It has a slight sheen to it, a bit like an eggshell finish. Some customers have told us that they have chosen this finish for the looks alone - it's sophisticated, and different.

Roof boxes pick up a lot of squashed insects as well as general road grot, and cleaning them without scratching them is next to impossible, just one of the things you have to live with and ignore. Scratching is not an issue with this new plastic - we've even used a nylon backed sponge, hot water and washing up liquid, and can see no evidence of abrasion. Extraordinary! (We'd generally recommend that you use hot water, mild detergent and an ordinary sponge, and we have to emphasise that scratch-resistant does not mean scratch-proof - this is an ABS plastic and if you go at it with e.g. a knife or a car key you will damage it.)

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 which 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".
