Opening Vent 

Some greenhouses have one opening vent and the larger units have two. The assembly of them 

is exactly the same. Assemble the frame of the opening vent as per the instructions. 

 

 

 

 

 

 

 

 

 

Note the hole in the centre of the bottom section, this is for the opening vent handle. 

 

 

Once the frame is assembled this needs to be slid into the ridge frame of the greenhouse. There is a 

rounded top on the top edge of the opening vent and this needs to be slid into the opening on the 

ridge. You may need to hold the opening vent at a sharp angle to allow this. Trial and error will show 

you the correct method. Once in place slide the fame into position.
