In addition to the other replies,

"Spectacle Blinds are combination of a Single Blind and a Ring Spacer fabricated, for field convenience, as a single unit. Weight limitations and the associated difficulty of handling heavy pieces in the field are the primary considerations in choosing either a Spectacle Blind or Figure Eight Blind over separate components. A good rule of thumb for selecting is use the Fig. 8 up to 14" in 150 lb. and 12" in 300 lb. piping. When supplied with a bolt hole in the tie bar, Spectacle Blinds can simply be rotated around a bolt to change Blind/Spacer orientation. Tie bars may be integral, single or double, and of material different from the Single Blind and Spacer, unless otherwise specified."
