Motor Retainer 29mm
29mm Motor Retainer
Both the 2924mm and 29mm motor retainers have the same mounting hole arrangement which allows both retainers to be used interchangeably on the same rocket - i.e. use the 29mm retainer when using 29mm motors, use a 24/29 motor adapter and 2924mm retainer when using 24mm motors.
Threaded inserts allow retainer to be added after model is built.
Note: This retainer requires a rocket with an aft centering ring to mount the threaded inserts. The body tube should be at least 1.9" ID to clear the retainer.
