Duotone iBase 2.0 + Joint (long pin)(incl. DUOTONE Pin Long) This traditional variant uses the legendary, slightly softer original Powerjoint. For safety reasons, an external safety line is attached. Since the built in DUOTONE 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 on the market. (Note: Not compatible with EPX. XT RDM)
