Fizan ND Expander 16 flexy

The Fizan ND Expander 16 flexy is a replacement plastic expanding mechanism for the twist-lock system on Fizan telescoping poles, sized for a 16 mm section — a heavier-duty diameter typical of three-section or sturdier models rather than the lightest four-piece poles. The function is the same as the smaller versions: the expander flares out inside the tube and, when twisted, grips to hold the set length. When the plastic wears out or cracks over time, the pole starts to slip or collapse under load instead of holding its height. Replacing this part fixes that without buying a new pair of poles. As with Fizan's other expanders, sizes aren't interchangeable — the 16 mm version fits the thicker sections, so it's worth confirming your pole's exact tube diameter before ordering. This is a purely functional service part with no weight or performance spec of its own, intended for owners of the matching pole model.
