These feet will raise any outworld leaving a 4mm gap which allows use of a 4mm heat cable.
They can either be fixed below using the original outworld screws or turned over and will rest under the outworld screws
These will be needed if modules are using heat cable links and the outworld needs to be connected at the same level.
S1 Outworld = 4 Feet
S2 Outworld = 6 Feet
