38mm Forward Closure Plugged Threaded

Tapped (threaded 5/16″ X 18 TPI) nipple on end of closure. It not only plugs the motor, but you can screw an eye-bolt into the threaded end to attach the shock cord right to the motor. Note: Eyebolt is not included. Use only if you decide to use electronics staging timer or an altimeter to control the ejection of the parachute and you don’t want the motor to control ejection.
