The BiWire was developed originally as a more secure alternative to a non-locking, or standard wiregate carabiner. In some cases, a carabiner can be opened by a loop in the rope, or gate coming in contact with another object. The patented double-gate design helps prevent accidental gate openings. To open the BiWire, the user must simultaneously push the outer gate and inward gate.
Screwlock or autolock carabiners can become inoperable due to ice, sand or other debris. The BiWire design does not utilize a mechanism to lock, and is therefore more resistant to natural contaminants and debris. This is advantageous when used in harsh environments by mountaineers or canyoneers.
• More resistant to contaminants and debris than other mechanisms
• Offers more security than a single wire gate
• Based on the strong rockD frame
