Child Safety Information Hook is provided free of charge for this product.   Hook child safety mechanisms are used to securely fit the control chain against the wall in such a way that it is fully stretched and prevents the control chain from hanging freely and children are nor able to remove them. Use of additional safety devices may reduce the risk of strangulation but the blind cannot be considered foolproof. Elimination of this type of risk can be achieved by keeping cords, chains, tapes and similar out of the reach of children. You must not proceed with the installation of the blind without having the child safety device installed as well. If for any reason you cannot find the device you must contact us via http://www.blindsuk.net/contact.html for a replacement and only after receiving the device install the blinds.
