Model Rocket Centering Rings

Model Rocket Centering Rings are used to center a smaller tube (or tubes, often an engine mount tube) inside a larger diameter one. Our rings are made from wound paper or plywood, depending on the size of the ring. Most are designed to be used in pairs. Some sizes of Centering Rings can also used as Engine Blocks in motor mounts.

Testimonials

Just wanted to thank you guys at ASP for your great service! I placed a last minute order for some First Fire ignitors and they shipped right away, and with some extra goodies in the package like epoxy mixing cups and brushes! I got the ignitors in time for my launch and it was awesome! Thanks again guys, I appreciate your speedy service! - Joe B.
