Fin Lock Ring 3 Fin - 19343

The ring fit perfectly into my build and the three retention tabs held the fin securely during launch. Assembly was straightforward and it feels much sturdier than the plastic piece I was using before.

Swapped out the old one during a rebuild and this ring seated perfectly over the fin slots with no sanding needed. The locking action is solid once twisted into place, so I’m confident it won’t shift mid-flight.

It's made of a much stiffer plastic than the old rings I've used, so it really locks down without cracking. One ring was enough to hold my heavy fin assembly firmly during the entire flight.
