E600 double triangular ductile‑iron access cover delivers a 675 × 675 mm clear opening with a 150 mm deep self‑aligning frame, certified to BS EN 124:2015 Class E600 (600 kN)—and optionally upgradable to Class F900 (900 kN) for the heaviest wheel loads—making it ideal for main roads, docks, and industrial yards.
Overview
The cover employs a three‑point non‑rock suspension system to eliminate cover movement under dynamic loads. It features two interlocking triangular leaves that lock solidly at 90°, ensuring stability under traffic and compliance with BS EN 124 Group 5 (E600) or optional Group 6 (F900) standards. With a clear opening of 675 × 675 mm, an 875 × 875 mm overall frame footprint, and a 150 mm frame depth, it integrates flush into prepared recesses for a seamless surface finish.

Benefits for End Users
Compliant with Highways Agency HA104/09 and DMRB CD 534 V0.1.0, this cover is widely accepted on UK and European highways. Its non‑rock design and solid suspension reduce seat wear and long‑term maintenance costs. Ergonomic handles and compatibility with BS 7903 lifting keys enable safe, one‑person operation during inspections.
Installation & Maintenance
The drop‑in, self‑aligning frame seats flush in a prepared masonry surround, ensuring quick, accurate installation with minimal levelling. Routine checks include inspecting hinge pins, lubricating locking bolts, and clearing debris from keyways—tasks completed in minutes to minimise downtime.
Compliance & Quality Assurance
Produced in ISO 9001‑certified foundries and third‑party tested (BSI Kitemark, NF, ICIM), each unit carries CE marking and adheres to BS EN 124-2:2015 specifications. Regular factory audits guarantee consistent quality and regulatory conformity across all batches.
