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.
