Main Products & Services
The Floating Locking Manhole Cover System (WSM648-110SRL) is a multifunctional safety manhole system consisting of a cover, frame, fall-prevention net, and locking device. Its one-touch push-and-turn, screw-free locking prevents theft and dislodging. When internal pressure rises during torrential rain, the cover self-floats while remaining secured, discharges stormwater (up to 200 m3/h), and reseats, eliminating cover blow-off accidents. The fall-prevention net protects pedestrians when the cover is open or missing, and the two-tier pyramid surface maintains slip resistance even after wear. It is verified by the PPS Innovative Product designation (2022-449) and the Ministry of SMEs and Startups performance certification.
