Wire gate carabiners became popular in the climbing world because of their light weight and high strength. The BiWire adds a totally new dimension to the concept by creating what is effectively a locking wire-gate carabiner. Two distinct and opposite actions are required to open the gate. This patent-pending design features an outer gate which protects the inner gate and prevents rope or hardware from opening it. Neither pressure from the outside or the inside of the carabiner can cause the gate to open. This makes the BiWire a safer alternative to a non-locking carabiner. The BiWire design is inherently strong and the gate is very resistant to dirt and ice. Even though the wires look thin, the BiWire minor axis strength is comparable to a conventional gate carabinger. Interior Length: 3.5 in. (88mm)

 

Note: The BiWire should not be used to replace a conventional locking gate carabiner because the gate is not physically secured by a sleeve. It could be possible for something to push open the inner gate allowing the possibility of the carabiner coming unclipped. So, use the BiWire as an alternative to a non-locker when you want extra strength and security.
