Semroc Engine Hook
Great item - allowed me to convert a rocket's engine retention from using masking tape for a friction fit. That became necessary on the rocket's maiden flight, when the engine was jettisoned instead of deploying the parachute, resulting in a full ballistic recovery. After crash damage repair, this hook was attached externally on the body tube, and has worked flawlessly since.
