Choice of carabiners for attaching the rope to the anchor

Warnings

  • Read the technical notice before viewing the following techniques.
  • It is important to fully understand the information provided in the technical notice before using this complementary information
  • Mastering these techniques requires training.
  • Consult a professional before attempting to perform these techniques on your own.

At the anchor, carabiners stay in place over a long period of time; monitoring them during use is difficult or irregular.

Requirements and needs differ depending on the situations, and the equipment to be connected.

During installation, there are often several items to be attached to the carabiner. The anchor is not always easily accessible; installation must sometimes be done with one hand.

Why this choice?

• The SCREW-LOCK system facilitates installation, as it can be locked just once, at the end of the operation. The entire operation can be done with one hand. With an auto-lock, the sleeve must be operated at each opening/closing of the gate and two hands are required to attach an item



• The frame shape and material (aluminum or steel) must be chosen depending on the situation (industrial, heavy systems, sport or recreation, lightweight systems...) and on the equipment to be attached (one or more ropes, pulley, PAW...)

• During installation, anticipate the situational risks and evaluate the possibilities of monitoring the connectors before and during use

• Do not leave a carabiner at the anchor without the ability to monitor it, if there is any risk of movement during use, cantilever loading or rubbing

• Once the installation is complete, verify that the connectors are correctly locked and positioned before using the system

• Whenever possible, back-up the system to avoid being dependent on the strength of only one carabiner

• Warning: the SCREW-LOCK sleeve can be opened by vibrations. During installation, be sure to rotate the carabiner so that gravity and vibrations tend to "close" the sleeve rather than "open" it
