USA Industries Inc. Spectacle Blinds

Spectacle blinds, alternatively known as spectacle flanges and figure-8 blinds, comprise two metal discs connected by a handle, resembling a pair of spectacles. While one disc is solid, the other features a hole or opening, enabling flow through the system when aligned with the pipe or vessel. We manufacture our figure-8 blinds from single machined metal pieces, eliminating the need for separate paddle blinds and spacers during pipe maintenance isolation.
