USA Industries' Spectacle Blinds are manufactured as a single piece of machined metal and eliminates the need for having a seperate paddle blind and ring spacer set to isolate your pipe. If a section of your pipe needs to be isolated for maintenance or repairs, the Spectacle Blind will make the process much easier for you!
Spectacle Blinds are most often mounted in the open position, which allows fluids or gases to flow freely. Consequently, to isolate a section of pipe in order to restrict flow of fluids or gases, all of the flange bolts holding the Spectacle Blind in postion must first be loosened. Subsequently, by rotating the blind from the open spacer side to the blank or closed side, this simple manuever closes the pipe and prevents flow, thereby isolating your pipe for repairs or maintenance procedures. Simultaneously, this step also visually identifies that the pipe is closed.

If you want the tie-bar to be made differently, let us know and we manufacture it just how you need it.
