A '''zeppelin loop''', also called a Rosendahl loop, is a secure, jam resistant [[:Category:Loop knots|loop knot]] based on the [[zeppelin bend]]. It is one of the few loops suitable for [[bungee cord|bungee]].
There are two possible variants, depending on how the end enters and exits the loop knot:
* The first type where
** The end enters the loop knot from the opposite side compared to the main part.
** It then seems to exit as a continuation of the loop beginning.
** The main part and the end are on the same plane as the loop.
* The second type where
** The end enters the loop knot perpendicular to the main part.
** It then seems to exit as a continuation of it.
** The main part and the end are perpendicular to the loop plane.
