24mm Motor Retainer (2 Pack, Estes)
Motor Retainers for 24mm Motors (2 Pack, Estes). Two-part retainer - threaded part is glued to the outside of 24mm Motor Tube (fits our T-50H Tube) and the other piece screws onto it to hold the motor in place during the ejection charge. Can be retro-fitted onto many models that are already built as long as the end of the engine tube is exposed far enough (about 1/2" or longer). For use with 24mm motors only. Comes with two sets per package.
