Spectacle blinds consist of a connected ring (spacer) and a plate (spade). If a piece of equipment needs to be inspected or removed from service then the plate covers the ring to form an airtight seal which consequently isolates a section of line or the piece of equipment. It provides a permanent or long term isolation device.
Our spectacle blinds, spades and spacers come in pressure ratings of 150lbs, 300lbs, 600lbs, 900lbs, 1500lbs and 2500lbs
