Ferrari has offered a closer look at its halo canopy protection device, which made a surprise appearance on Kimi Raikkonen's SF16-T during testing this morning.

The team fitted an early prototype device to Raikkonen's car, the Finn proceeding to complete two installation laps with the device before it was removed. It won't be used again for the remainder of this test.

Though the FIA has been busy testing various concepts for cockpit protection, this is Ferrari's take on it and is the first time such a device has been seen in public.

Allowing the media a closer look, a Ferrari spokesman offered some details and explained how this design and the way it is fitted to the car would have to go through a lot of changes.

"The metal structure, which is thinner and hopefully better looking, it will probably be bolted in the chassis itself.

"I have been asked whether there are hinges or something which can be lifted just in case of an accident for the rescue team to move probably. They probably have to chop the metal because if you have hinges and you have distortion, you can't be 100 per cent sure if they got twisted and make it impossible for the rescue team to lift it.

"We used screws but it is not the way it is supposed to be, it is supposed to be attached to the structure when it is finished."

Asked about Raikkonen's impression of the device, he described visibility as 'OK'.

"The first comment was it's OK, but it was just an installation lap. It was just to check for visibility."
