The DMM Ultra O Durolock 4 Way Locking Karabiner is a popular choice for tree surgeons due to its lightweight, durable construction and easy-to-use locking mechanism. The oval shape of the carabiner allows for multiple attachments to be made without crowding, and the deep basket helps to keep devices centered and aligned.

The Durolock gate is a four-way locking mechanism that is designed to minimize the risk of accidental opening. To open the gate, the user must rotate the sleeve and push the gate open. Once the gate is released, it will automatically lock back into place. This makes the Ultra O Durolock an ideal choice for use in complex rigging applications.

The Ultra O Durolock is also made from high-quality aluminum alloy, which makes it both lightweight and strong. It has a breaking strength of 24 kN, which is more than enough to handle the forces encountered in tree surgery.
