FRAME
It is obtained from a single cast, its stability is guaranteed through a double throat supporting area, creating a metal to metal coupling 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 the 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 process is obtained through the insertion of
specific handles in the blind holes of the surface .The filling basin has a height of 70 mm and it can
host any kind of filling material. All the covers are interchangeable.
