The Type SM door provides a cost-effective solution for access to underground vaults that do not require the use of a flush-mounted door. It features a concealed internal mounting flange that makes installation easy and secure. The doors’ overlapping cover design is fully-gasketed to shed water and prevent debris from entering the areaway, making it ideal for applications where the infiltration of contaminants is a concern.
