Certain products are displayed as 'contact us' but this does not mean that the item is out of stock. Please contact us if you are interested in these products. Some products are 'contact us' because we have dealer agreements in place that are designed to protect premium models. This helps to ensure that they are used with the right equipment and installed correctly to preserve the quality of those items and their brands. Other products are more specialist and therefore we like to speak to our customers about their requirements prior to the purchase of these items.
