Spectacle Blinds are applied to systems which regularly need to be separated from other connections, since they are usually permanently installed in the line.
Spectacle Blinds, Spades & Ring Spacers
Designed to blind pipelines, either temporarily or permanently.
Mac-Weld spectacle blinds are manufactured from a single piece of plate, providing the strength, quality and precision needed for the toughest job. Also called “spectacle flanges”, our blinds are available in a variety of configurations, blind types and bore designs.
Spades and ring spacers are similar to blinds, except they are not attached to each other. With larger flange sizes, the spade alone can weigh several hundred pounds. Separating the two removes the unneeded weight from the flange connection. Spade and ring spacers can also be an advantage if space is limited.
