Using this daisy chain is quite straightforward. First, make sure you're in a safe climbing environment. Attach the double - loop end to your anchor point. You can then adjust the length of the lanyard by moving it to different loops as needed. When climbing, ensure that you don't put too much stress on a single loop. As for maintenance, after each use, check the daisy chain for any signs of wear, such as fraying or cuts. If you find any damage, stop using it immediately. Store it in a cool, dry place away from direct sunlight to prevent the polyamide material from degrading over time.
