Cover frame | 3-gang | white | Sedna Design | Schneider Electric | SDD311803
Schneider Electric Sedna Design SDD311803 is a white 3-gang cover frame for switches, sockets and other Sedna Design mechanisms. It combines 3 mechanisms into one neat block.
Key point:
Several points in one place look like one unit, not separate devices. The frame can be installed horizontally or vertically, and any Sedna Design mechanisms – switches, sockets, data outlets – can go into its 3 places.Gangs

White RAL 9003How it works
First, Sedna Design mechanisms with fixing frames are installed in the boxes.
The cover frame is placed over the mechanisms and locked, then rockers or socket covers are fitted.
Result: a flat, neat installation point with no visible box edges.
