You can check on the following link to see all the schematic diagrams for the Fiamma F45 range of awnings.

In the products descriptions to determine if you need a LH (Lefthand) or RH (Righthand) part then stand at the side of the vehicle looking at the awning in front of you and LH refers to the leg / arm / end cap etc on your left side and RH parts are the parts that are are your right side.

Note: The L letter in the product name i.e. F45L or F65L means a Large awning typically 4.5m or longer (although some F65L awnings are 4m in length and this is shared by F45s and F65s models which go up to 4m in length also.)
