Allegro's new 9510-50 Manhole Ventilation Passthru is a really cool piece of equipment. It is a incredibly simple way to ventilate a space while at the same time still allowing access to the space for your workers. It is an excellent and less-expensive alternative to the Saddle Vent system.

- the Collapsible duct springs back into shape once worker is down into the manhole
- the ducting is vinyl and polyester with PVC coating and heat resistant up to 180° F
