Octopus Safety Stopper
$17
The Octopus Safety Stopper prevents your lanyard from getting stuck on bottom of the rope. The almost-flat upper part gives a clean stop to your carabiner, while the lower part, with its conical shape, allows the cable of your lanyard to be “expelled” towards the outside, with no grip to get it stuck. Its bright fluorescent yellow color makes it more visible.
Specially made for ropes with 10 to 12mm diameter, but it's also possible to use it with smaller ropes, down to 8mm.
Regarding the mounting process, the stopper is divided in two parts. A simple knot is placed in its center, and 3 stainless steel screws (standard cross-head) make it easy to finish putting it in place.
