The Petzl Ring Open is a versatile semi-permanent connector with a gated opening system for easy installation of ropes, sewn terminations, and fixed attachment points. Its round shape ensures multi-directional strength, distributing forces evenly in all loading directions. Lightweight, strong, and easy to use, the Ring Open is a reliable connection point for climbing, rigging, and professional setups.

The Semi circular or half moon Maillon Rapide is ideal for securing caving harnesses, it is commonly used for the junction of 2 connecting points on a harness. Screw links are a lot more secure than karabiners so are essential if there's a possibility that the connector may be cross-loaded.

When you need a reliable connection but need to be able to affect an immediate release this is the karabiner for you. Ideal for helicopter and across river rescues. Double button locking with multiple safety mechanism and a breaking strength of 40kN. Paragliders are able to separate the pilot from his/her glider when using a dirigible rescue system.
