ultra non-slip cord lock/line lock for thin shock cord

I had a project with a very thin shock cord...around 2mm. The cord locks I was trying to use kept slipping. Thin shock cord is fairly slick and as it stretches it shrinks in diameter making it tough to grip. This line lock has 3 holes providing multiple areas of friction and grip. The 3rd hole which is not normally found on cord locks like this help to pull the cord more firmly into the teeth on the bottom.

The teeth on the bottom are not generally seen in these types of cord locks and represent the combination of line lock technology from two different common solutions.

Free to use as you please, although I enjoy seeing likes or comments if this helps someone!
