Spectacle blinds, spades and spacers
We produce spectacle blinds, spades and spacers used to positively isolate lines for maintenance or testing.
One side of a spectacle blind is solid, the other is a ring. In service the ring sits between the flanges; to isolate, the blind side is turned in.
In large sizes separate spades and spacers are preferred to a spectacle blind.
