Fuminas DN 300 plugs are designed for 300 mm access boxes. They can be used with floor or not, since the cover is double sided (with two sides of use). In this way, they provide better finishing in internal and external areas (streets and sidewalks). They follow a system of siphoned channel to avoid the passage of insects and odors by the well of visit. In addition, they allow simple two-point locking, which makes it easier to lift the cover for maintenance. Made with ductile iron FE 50007 (Class E50).
