OFNR (optical fiber nonconductive riser) cords prevent the spread of fire from floor to floor within buildings. Use them in vertical spaces, such as shafts, between floors.

Cords with SC connections have push-pull connectors that lock in place with a tab.

Cords with ST connections have twist-lock spring-loaded connectors that secure in place with a bayonet lock.
