Isabella Magnum 400 Silver LogoIsabella Magnum Flint 400 Porch Awning

The Isabella Magnum Flint 400 is a porch awning from Isabella that has been developed for people who are likely to be touring around rather than pitching in one place. Quick and easy to put up and touring friendly it is supplied with Isabella's CarbonX poles. With the Magnum 400 Flint, you get a spacious touring awning with a depth of 2.5 metres and a width of 4.0 metres.

A nice feature of the porch awning is that the front and side panels can be either rolled down or completely removed giving you a number of options for ventilation. Mosquito nets are also provided ensuring you can have windows open and enjoy that great holiday read without the worrying of letting in the insect world. 

If more space is required, inside or out, the Magnum 400 Flint can be extended with an Eclipse front sun canopy (specially designed for Magnum), Cosy Corner (specially designed for Magnum), and an annex giving you an extra bedroom or additional storage space.

The main awning material is called Isacryl and has been developed by Isabella specially for awnings. It is highly breathable and therefore helps to maintain a comfortable and enjoyable climate inside the awning.  The roof material is Isabella's IsaRoof 285 - an ultra-durable UV-resistant polyester textile, treated with three layers of breathable acrylic.

The awning is supplied with Isabella's CarbonX poles, these are light carbon-fibre reinforced fibreglass poles and suitable for permanent and touring caravanning.

The Magnum Flint 400 is suitable for caravans with a rail  height of between 235 and 250cm. 

Magnum Flint is part of the Flint style concept, i.e. a greyish colour scheme inspired by flint as a material.

The Isabella Magnum Flint 400 porch awning comes with a number of items as standard which include, a set of curtains, a wheel arch cover, a draught skirt, veranda pole, FixOn, awning bag, pole bag and peg bag and a peg remover.

Isabella Sizing Chart IllustrationTo Find The Correct Awning Size For Your Caravan

Full Awnings
To find the correct size of awning for your caravan you need to find the 'A' measurement. This is often given in handbooks by the manufacturer of the caravan, but if you cannot find the 'A' measurement then you can measure it yourself.

Position the caravan on even, level ground. Measure from the ground level at a point directly below the awning rail at the front of the caravan to the ground level point directly below the awning rail at the rear of the caravan. You can do this quite easily using a piece of string or chord. This measurement will be the red line shown on the image.

Porch Awnings
Generally, you do not use the 'A' measurement for porch awnings. Instead you will want the awning rail height from ground level - shown as 'H' on the diagram. Unlike the awning rail height which is a fixed dimension, the width of the awning - shown as 'L' on the diagram is variable. Some people do not like to fix an awning across a window as shown on the left hand side of the diagram, so they would probably buy an awning either with a smaller width or wider width if room permits. Essentially the choice is yours to make.
