Circular solid top access covers are for 600mm & 700mm diameter clear openings.

Hemelock covers are single part covers manufactured from a resin composite. The covers are lighter than traditional cast iron covers, are locked down with unique twist action bolts and offer excellent chemical resistance particularly for petrochemical applications.

Hemelock access covers are tested to class B and class D loads (EN124)* and a special lifting key to fit the central lifting boss is available, please inquire.
