Open cavity cover/locking plate




For some housings a small, thin screwdriver can be used, for others no tool is required.
The secondary locking on this type of housing is released by setting the cavity cover/locking plate in the open position. There are two positions, open or closed.
- Lift up, push or unclip from the locking plate
A "click" can be heard when the plate unlocks and is in the open position.

Note! If the housing has a long, narrow locking plate check that it opens completely and not only along one edge. Work loose the locking plate along one entire long side.
