"The Pure Screw III from Edelrid is a robust and versatile locking carabiner designed for all vertical disciplines such as climbing and bouldering. With its special nose geometry and keylock closure, it guarantees optimum handling when clipping in and out, making it a reliable companion in any situation. The HProfile construction ensures that the material is used optimally, while the weight remains minimal, which is particularly advantageous on long climbing tours."
"The carabiner is available in different versions, including a slider, screw or triple lock version, so that the right solution is available for every need. The large rope support surface minimizes material wear and increases the longevity of the product. Another plus is the high open strength, which offers additional safety during use, whether climbing or bouldering"
