This F900 multileaf manhole cover delivers extreme load capacity (900 kN/90 t) for airports, docks and heavy‑industry zones, thanks to EN124:2015 Class F900 certification. Its hinged multileaf design with a security handle enables one‑person operation and tamper resistance, reducing downtime and maintenance costs. With a 750 × 750 mm clear opening and 120 mm frame height, it fits standard square access points while ensuring robust substrate support.

Overview

This F900 multileaf manhole cover is designed to withstand test loads up to 900 kN (90 tonnes) per EN124:2015 Class F900 requirements. The 750 × 750 mm clear opening accommodates standard square access points while the 120 mm frame height ensures robust load distribution into the substrate. A double triangular access solution with a security handle provides ergonomic lifting and prevents unauthorized opening.
