Our B125 gas cover is engineered to EN 124 Group 2 standards, capable of withstanding a 125 kN (12.5‑tonne) test load—perfect for footways, pedestrian areas, and car parks with occasional vehicular access. With a precise 120 × 120 mm clear opening, it fits standard gas‑valve chambers, while the 50 mm high frame ensures a flush, trip‑free surface integration. Constructed from GGG 500‑7 ductile iron, this cover balances outstanding strength and corrosion resistance with manageable weight for safe, ergonomic installation.
