If however you want a simpler non SSF installation, we also include those components too. Once you decide the installation instructions will guide you on the relevant steps. There is no change in functionality between a SSF and non-SSF installation.
If you are not sure whether or not you need an SSF installation. We would recommend checking with your insurance company as it may depend on the value of the contents within your property.
