GTS is the only extractor specifically designed for opening Pont à Mousson manhole covers with a rotational locking system (<Closed-Open>), characterized by the absence of traditional hooking points. Created to meet a real need, which until now had no dedicated solution, GTS represents a technical innovation in urban maintenance.

The GTS extractor is the only tailor-made extractor for this type of manhole cover, providing operators with an effective, safe, and regulation-compliant tool.
