Positive Motor Retention

Introducing the PML Positive Motor Retention System.  The supplied brass threaded inserts screw into holes you drill in your rocket's centering ring, and stay with the rocket.  Then, the laser cut, stainless steel Tripod motor retainer slips over the nozzle section of the motor.  Install the 3 socket head bolts with the provided wrench into the threaded brass inserts, and the motor stays in until YOU decide its coming out!  No more worries about friction fitting with masking tape, and no more expensive "kicked" reload casings.  Equip all your rockets with the PML Positive Motor Retention System!
