Cluster Rings

Cluster Centering rings are used to keep several motor tubes properly nested within the airframe tube.

Here you will find cluster rings for larger motor tubes (29mm and 38mm). We offer centering rings for low, mid and high-power rockets, you can change your selection by clicking buttons below.

We can also cut custom cluster rings, let us know what you need. Turn-around time on the special order rings is usually 2 days.
