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 are supplied with a special lifting key to fit the central lifting boss.
