Slot fillers are required to fill empty or partially empty slots in the Control4 Panels. Each Control4 panel comes with a set of Slot Fillers (one 2-pack of Slot Fillers in the C4-DIN-2PAN and two 2-packs of Slot Fillers in the C4-DIN-5PAN). Additional 2-packs of Slot Fillers can be ordered as needed.
