We have checked and this opener fits all popular freestanding greenhouses up to 10’ wide made by Eden, Halls, AGL and Simplicity. It also fits Gardman greenhouses but not Palram greenhouses. For other makes you will need to look at our picture. The flexible design ensures that this unit can be fitted to most greenhouses but no guarantee is given that it will fit a particular model.IMPORTANT NOTE:This vent opener also fits larger lean to greenhouses which are at least 4' deep but not smaller lean tos. This is because the cylinder hangs down and protrudes whenever the vent is not fully open. In a smaller lean to greenhouse e.g. 2'x4' or 2'x6' the cylinder would be obstructed by the front wall.The picture shows the standard vent opener. The two fixing clamps have been fitted to the aluminium frame.For most aluminium greenhouses the opener can be fitted using the clamps. The smaller vent bracket features elongated holes which allows you to position the clamp in just the right place. The larger frame bracket fits the greenhouse frame with four pairs of holes to help you position the clamp in the best place. For most wooden greenhouses the clamps are not needed but you will need wood screws which are not supplied. The elongated holes in the smaller vent bracket allow you to position the clamp in just the right place. The larger frame bracket fits into the greenhouse frame with four pairs of holes to help you position the clamp in the best place.For some aluminium greenhouses the clamps do not fit. In many cases the opener can still be fitted using the vent bracket with its elongated holes and the frame bracket with its four pairs of holes. You may need to drill some small holes in the vent frame and the greenhouse frame in order to secure the brackets. ## Features - Heat operated, opens and closes roof vents automatically Fits most popular greenhouses Multiple holes to suit most greenhouse frames Clamps and fixings included Any UK address included, mainland or offshore, except the Channel Islands ## Images ![AUTOMATIC GREENHOUSE WINDOW OPENER - HEAT SENSITIVE SOLAR POWERED AUTO ROOF VENT - Image 1](https://m.media-amazon.com/images/I/51J5WKwd7+L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good price for this item *by B***P on Reviewed in the United Kingdom on 1 September 2016* Good price for this item, well made and seems to work okay in the time I have had it fitted. Seller was first class delivered on time and item well packaged. Easy to fit to a standard B&Q greenhouse. You can either drill the frame to fit or just attach to the existing framework. This method has worked for me in the past as well with different window openers. Would certainly buy again. ### ⭐⭐⭐⭐⭐ Cracking value *by G***X on Reviewed in the United Kingdom on 4 November 2015* Very good value for money and quick delivery. Some people have mentioned problems with lining up the existing holes in their greenhouse with this opener but there is actually no need to do so. The clips fit onto the edges of the frame and the window with no trouble at all and the screws will not touch the glass of your greenhouse if you have the normal rubber trim in place. I have been using these for years with no problems at all. ### ⭐⭐⭐⭐⭐ Easy Fit Vent *by R***N on Reviewed in the United Kingdom on 6 May 2014* Bought one of these couple of years ago on my and works brilliant,on my all/min. greenhouse.Bought it for my grandsons greenhouse,which is a wooden one and the window is a bit more heavey than mine.Fitted it on his greenhouse and works brilliant.Going to buy him 2 more for other windows.These are good quality east peasy to fit and cheap.Well worth the brass. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/79532949-automatic-greenhouse-window-opener-heat-sensitive-solar-powered-auto-roof](https://www.desertcart.hr/products/79532949-automatic-greenhouse-window-opener-heat-sensitive-solar-powered-auto-roof) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-20*
