The 152/B probe is made of Perlon, known as the best nylon available.

White in colour, with a diameter of 4mm.

At the ends there are two fixed crimped terminals: a flexible curve-guide head and a tensioning eyelet.

It easily overcomes 4 bends in both the rigid pipe and the corrugated pipe, avoiding installing the section breaker box.

If accidentally bent, it can be straightened easily and returns to its natural position at 80%.
