The Onis Line Blind replaces spectacle blinds, slip blinds, and figure-8 blinds. One operator can use an Onis Blind and isolate up to a 50" in a few minutes without using any tools or cranes. Onis Line Blinds can be used in any service and will reduce maintenance costs, increase production time, improve safety by reducing exposure, and minimize emissions during blinding.
