A range of single part, solid top composite access covers with excellent chemical and fuel resistance for hostile environments.
Hermelock covers are made from glass fibre reinforced polyurethane and therefore are low maintenance, rust free and lighter than traditional cast iron covers to comply with the Work Cover National Code of Practice (maximum unassisted lifting weight of 55kg). A special lifting fork is available which reduces to cover weight 9kg.
Unique twist action bolts secure the cover to a polyethylene frame to activate a double hermetic seal which in combination with a neoprene gasket provides a gas, water and odour seal.
Designed to EN124, these systems are designed to load classes up to D400kN (E400KN – AS3996). Each cover has an anti slip texture allowing for safety of passage in wet weather
