Details

The bushing is ready for connection with MV clamp and all earth contacting components are made of StSt (V4A).
Sealing is performed by the pressing of the neopren disks against the brickwork/wall (fixed and loose flange).
Installation can be implemented from inside. The threaded rod can be held by the lock nuts (inside) when tightening the screws.
