The STORMSURGE Access Assembly from EJ is an innovative manhole cover assembly that allows water to flow during major rain and flooding, but the cover remains attached so it seals itself after the event. During a storm surge or backflow event, it can lift up to 16 degrees, enabling water to flow out and relieve pressure. The locking arm and hinge restrain the cover and allow it to return to the seated position once the surcharge subsides. The assembly is heavy-duty traffic rated, made of ductile iron and has a cover that is permanently attached to the frame. There is a safety catch at 90 degrees to prevent unintended closure and a security bolt allows for controlled access and acts as a theft deterrent. 800-874-4100; www.ejco.com.
