    This was the only duct system I could find that allowed me to discretely fit an extractor to a gable end in a Victorian property without altering the appearance of the building aspect. All the square grills were too wide and would have meant more time consuming alterations, this kit needed minimum fuss and was ready to use after 15 minutes. Brilliant.

    Superb piece of kit that can be fitted from inside, allowing quick and easy installation of a standard 100mm extractor. No need for ladder or scaffold outside, cuts down installation time immensely.
