Extra parts: 1 piece of Endeløs panel. No ribs attached.
If you need 1 extra support leg for your Endeløs setup in order to reassemble and build a new setup, this is the one. If you want to make one complete Endeløs module you need 2xsupport legs (and 4 x ribs, purchased separately). Don't forget to add the right screws and brackets, if you need that as well.
