Duotone iBase 2.0 + Joint (long pin)
This traditional variant uses the legendary, slightly softer original Powerjoint fitted with a Mistral type of Long Euro pin. For safety reasons, an external safety line is attached but is not going to hold the joint together if the UJ fails.
Since the Euro pin has been seen as the standard on the market for decades, the joint can be fitted directly to approx. 90% of all mast extensions but you may need to shorten the pin length (in most cases.. hacksaw and file required).
If you are not sure.. ASK!
