KONG Back-Up ANSI Orange/Black + Ovalone Carbon Twist Lock ANSI OS – One-Handed Fall Arrest

Meet the KONG Back-Up ANSI Orange/Black with Ovalone Carbon Twist Lock ANSI OS, a compact fall arrester designed for one-handed operation. This device follows the operator in both directions, stopping a fall while allowing controlled movement. By switching lock modes, it also serves as a positioning device or a standard locking device. Its advanced design minimizes shock loading on ropes compared with traditional self-locking toothed cams, supporting semi-dynamic loading scenarios.

When used with a NO-CUT LANYARD Ø 12, in compliance with EN 567 and UIAA 104, it integrates smoothly into rope-access setups. A connector is included for quick attachment, helping you set up your system faster and with fewer loose parts.

Why choose the KONG Back-Up system?

• One-handed operation for easier handling in constrained spaces or at height
• Bidirectional following mode that helps maintain flow and control during movement
• Semi-dynamic braking reduces abrupt rope loading, protecting the rope and device
• Flexible lock modes for arrest, positioning, or standard locking tasks
• Compatibility with EN 567/UIAA 104 standards and included connector for ready use

Real-world uses and scenarios

In industrial rope access, aerial work, or climbing routes, the Back-Up supports workers who need reliable restraint without interrupting mobility. The vivid ANSI orange/black color increases visibility on crowded job sites, and the compact form fits into tight spaces where other devices struggle.

• Rope access and rescue teams can benefit from the device's safe stopping behavior
• Maintenance crews will appreciate quick one-handed operation to re-position or lock the line
• Outdoor climbers may use it for belay management during transitions

Technical notes: The connector is included, and the product is designed to manage strong stresses with a semi-dynamic profile. This is not a guarantee, but a design characteristic that may offer safer rope handling in certain scenarios.
