It is obtained from a single cast, without gasket, its stability is guaranteed through a metal to metal coupling. Externally, the outside border is flanged in order to optimise its hold in the cement and the insertion of anchoring bolts.
It is square in shape, it comes with two dead holes, which allow the insertion of suitable handles to lift the cover (supplied on request). All the covers are interchangeable. The upper surface is designed to be non-skid to allow the complete flow of water and avoid the creation of ice.
