Aluminum Manhole Shield
The manhole shield is an essential tool that helps prevent ground water and debris falling on a technician working in a manhole.
This 12″ high shield is made of lightweight aluminum and has a pneumatic seal that keeps ground water from flowing into the open manhole. Just inflate the tube with 5-10 lbs. of air or nitrogen to form a water-tight seal. No clamps or sealing compounds required. The manhole shield (reversible 27″ & 30″) fits most communications manhole openings.
Also included is one high quality, puncture resistant inflatable sealing tube to keep surface water and mud out of the manhole vault. The tube can be removed and placed on either end of the shield depending on the manhole vault being sealed.
