FRAME
It is obtained from a single cast, its stability is guaranteed through a double throat supporting area, creating a metal to metal coupling system, thanks to the interposition of an EPDM gasket, this is studied to obtain a watertight/waterproof sealing. Inside there is also a special provision to host, if necessary, the glass reinforced plate (GRP).
COVER It is square in shape, it ensures a high stability due to a depth of insertion over 50 mm, the EPDM gasket inserted in the throat, which is located in the supporting area, and the locking system with stainless steel screws. The opening is obtained through the insertion of specific handles in the blind holes of the surface. All the covers are interchangeable. The top surface is antiskid and it allows the complete flow of water.
