Rocketarium's 18mm motor retainers are precision machined from aluminum.  For use with all 18mm motors (such as Estes and Quest 18mm A-C motors and Aerotech single use and RMS 18mm motors), these fit Estes-size BT-20 body and motor tubes (slightly thicker 18-mm paper tubes, such as those from LOC or Aerotech, can be sanded to achieve a good fit).

No tools are required to use these retainers. For motors with thrust rings, just screw off the cap, insert the motor, and screw the cap back on.. Motors without a thrust ring must be friction-fit.
