Spades and Ring Spacers

Spades (single blinds) / ring spacer
Spades and Ring Spacers are basically the same as Spectacle Blinds, except that both are not attached to each other.

Spades and Spacers be applied in systems where maintenance is often not necessary, or in applications with large pipe sizes. Spectacle Blinds, Spades and Ring Spacers should be made from a plate or forging specification, approved for use by ASME B31.3, of essentially the same chemical composition as the mating flanges and piping involved.
