Centering Rings

Centering rings are used to place a small tube nested within a large one. For example, a CR-2050 centering ring will center a BT-20 body tube inside a BT-50 body tube.

Fiber centering rings are made of thick card stock. The are usually flat and sized to fit tightly in the outside tube and for the inside tube to fit tightly inside the ring. You may need to sand the inside or outside of the ring to fit your tubes.

Cardstock centering rings are made of a slightly less stiff type of cardstock than our fiber centering rings.

Paper centering rings are made of rolled paper and are often used to center motor tubes or as thrust rings. Sometimes motor tubes are thicker than regular tubes so you might need to peel off a layer of paper from inside the centering ring so that it fits over the motor tube.
