Two genuine velux window opening restrictors ZOZ 010KI to fit windows labeled GGL / GGU / GZL GZL-B / GLL / GLL-B / GLU. Brand new. Comes with metal restrictor, fittings, window lacquer and instructions. Accidentally bought too many as I had thought I needed for both sides of the window which is incorrect - you only need one of these per window so the two will allow for two windows to be fitted. A child key can be bought direct from velux or third party if needed to enable these to be locked. Please note this price if for two restrictors - happy to be contacted directly if you only want to purchase one.
