 SAFETY FIRING HEAD NO-GO
Product Series: TCP NG 1500 ***
The LRI Firing Head Safety No-Go provides protection from accidental firing when an insert no-go is not being used. (eg. When roller drop bar is being used, or when logging near the firing head is necessary.)
It is simply placed on top of the LRI Mechanical Firing Head before the first coupling and pup joint are made up.
Features:
- Allows LRI Roller Drop Bar to contact the firing pin.
- More economical than running a special firing head with an integrated no-go.
