Spectacle blinds consist of a ring (spacer) and a plate (spade).
In the event of an item of equipment being shut down, the plate covers the ring to form an airtight seal. Our spectacle blinds are designed to ensure that an item of equipment can be securely blanked off, with no possibility of leakage in the valve.
Because safety is so important to the function of our spectacle blinds, we assure that they are tested exactly to clients specifications. Our
