24mm Plastic Rocket Motor Retainer for our thick-wall motor tubes. Works also for Estes and LOC Precision thick-wall paper tubes (1" OD).

The perfect accessory for all 24 mm engines! The Motor Retainer Set allows you to quickly load and unload a motor and works with thick-wall 24 mm motor tube (BT-50 with thicker wall and therefore slightly large outer diameter.)

Once installed, the retainer doesn't require any tools to operate. Simply install the model rocket motor, and screw on the cap.

The 24mm retainers also allow you to use 18 mm RMS system with rockets requiring 24 mm black powder motors. All you need is to install the retainer and add 24 to 18 adapter
