The Implications For You
All TRUBLUE devices and replacement webbings currently only ship with the TRU-Lock Carabiner. When ordering the TRUBLUE Auto Belay or replacement webbing, you have the option of choosing the TRU-Lock Carabiner as your webbing connector.
An novel integrated attachment point for a secondary connection to the climber is present on the TRU-Lock Triple Stage Locking Carabiner. To reduce the likelihood of erroneous user attachment, this inbuilt backup option can be utilized for competitive or leisure climbing.

TRU-Lock Dual Connection Carabiner
Used Components
The EN362 triple locking connector and an EN566 sling that can be securely girth hitched to the TRU-Lock Carabiner make up the secondary connection hardware. Materials like aramids and UHMWPE (Dyneema, Spectra) shouldn’t be utilized because they often don’t work with girth hitch connections because their strength is significantly reduced. With this type of use, materials like nylon and polyester are typically more appropriate. Due to the high likelihood of cross loading or multiplying forces through constrained motion and the associated leverage imposed on the TRU-Lock secondary connection point, metallic connectors are not permitted.
Climber Connection
Assuming that such an attachment technique is operationally compatible, a user may be linked to both primary and secondary connectors at the same rated harness attachment point or to numerous harness attachment points. When possible, connectors’ gates should face in the other direction.
Considerations
Additional factors that may vary depending on the operation include:
- Secondary connector length: It ought to be as small as possible and not be loaded during normal operation.
- Inspection: Girth hitches should be loosened and inspected regularly to check for wear
- Secondary Connection Loading: The secondary connector has a tendency to rotate into a potential cross- or gate-loading configuration because it is not loaded when in operation. To preserve appropriate orientation and guarantee that the connection stays connected to the TRU-Lock Carabiner and is not left on harnesses after use, think about using a lanyard keeper or caught eye carabiner.
Recommendations for Secondary Connector Products and Systems
Keep the following guidelines in mind as you plan how to construct the secondary connector:
- Nylon or polyester should be used for the lanyard.
- You should enable the lanyard to be girth hitched.
- The lanyard needs to have EN566 certification.
- The carabiner needs to be triple-locking and EN362-certified.
- Lanyard keepers are highly advised to secure the carabiner to the sling.
The majority of quickdraw slings made of polyamid or polyester that are 13mm and larger are suitable, but the system shown below is an example that satisfies the criteria for the secondary connection hardware:
