Allegro's Manhole Ventilation Passthru (MVP) is the only manhole system that combines a low-profile air vent, a 90° elbow and mounting all in one. The MVP unit includes a collapsible duct for easy entry and a small storage bag with a quick-release drawstring. The collapsible duct quickly springs back to it's original shape once the worker is down. Ducting is made of vinyl and polyester with a PVC coating to make it durable and heat resistant up to 180° F. The manhole cover fits perfectly into the flat channel corner, providing excellent stabilization. Made from Linear Low Density Polyeithylene, the MVP is sturdy yet compact and lightweight.
