Thrubeam® B125 BM Manhole Cover

The Thrubeam® B125 BM Manhole Cover is a composite access cover designed for pedestrian, industrial, and utilities use. It meets the European EN 124Class B125 standards, ensuring high structural performance and extended working life. The cover is made from advanced fibre glass composite, which resists chemical attack, diesel, petrol, salt, and water, and does not support combustion. It features embedded aggregate tread for permanent anti-slip performance with a PSRV of 60, even when wet. The cover can be supplied solid or vented, with locking mechanisms and optional integrated restraint devices for security. It is non-corrosive, electrically non-conductive (can be made conductive if required), and transparent to radio waves to improve asset management.
