Used to pot the kevlar in the termination at the vehicle side.
We had 1-2 meter length of kevlar. Made a knot at the end. Between the knot and the termination we placed a sprocket inside the kevlar bundle. This sprocket was used to spread the strings of kevlar equally.
Everything was mounted vertically for potting by hanging the kevlar-knot on a hook. Because of the weight you get some tension on the kevlar.
Now every was ready for potting with Wire Lock.
