Allegro Manhole Ventilation Passthru (MVP) 9510-50

Available - Usually ships in 2 - 3 days
Allegro has come up with the first all in one manhole entry system that is permanently connected in one piece. There is no more taking apart and putting together. This unit has a collapsible duct which is stored into a small duct bag attached to the end of the unit. When done using the Manhole Entry System just fold up the duct and store. When the system is needed again just release the draw string and put into the manhole.

With the Allegro Manhole Entry System you have a system that combines a manhole air vent with a 90 degree elbow into one unit. The ducting is a vinyl and polyester with a PVC coating that is heat resistant up to 180 degrees F. There is a lip that holds the unit into place on the edge of the manhole. It lies against the side of the manhole making entry in and out easy.

This unit is very lightweight because it is made from Linear Low Density Polyethylene. This unit stores in a small carton making it inexpensive to ship adding one more bonus to the reason this unit is a good fit for your team.
