This 200 × 200 mm clear‑opening B125 manhole cover and frame features a drop‑in, single‑seal design cast from GGG500/7 ductile iron per ISO 1083 for outstanding strength and durability. Fully rated to Class B125 (125 kN test load), it excels in pedestrian and light‑traffic settings, ensuring safety and regulatory compliance under BS EN 124‑2:2015. The precise labyrinth seal prevents water ingress, debris buildup, and odour escape, while its simple drop‑in mounting and 300 × 300 mm outer frame (24 mm depth) enable rapid removal and re‑seating during maintenance.
