Manhole Ventilation Pass Thru MPN:9510-50

Allegro® Industries Manhole Ventilation Passthru (MVP) assembly is designed to help you maintain and redirect air flow into manholes, sewers, and tanks, with minimal restriction. The system—low-profile manhole air vent, low-profile 90° elbow, and easy-entry duct—is compact, lightweight, and not statically conductive. The collapsible duct is packed in a small storage bag with a quick-release draw string to drop it into the manhole. The duct springs into shape once a worker has entered. Once the low-profile system is installed, flat-channeled corners let the manhole cover fit into place for stabilization.
