Rock Exotica rockD BiWire Carabiner. C2 BW (Red) C2 BW-B (Black). From $13.95. This patent pending design features an outer gate in addition to the normal inner gate. This provides extra protection for the inner gate and prevents rope or other objects from inadvertently opening it. Use the Bi-Wire as an alternative to a non-locking carabiner when you want extra security. The Bi-Wire design is inherently very strong. The outer wire gate is also much stronger than a conventional locking sleeve. Available in Red or Black.
