## Description

Automatic Greenhouse Roof Window OpenerThis quality roof vent opener fits most common types and sizes of greenhouse vent. 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.

### ⭐⭐⭐⭐⭐ 







  
  
    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.
