Allegro Manhole Shields

Manhole Shield keeps mud and water away from workers. This strong, rugged, lightweight, fade-resistant polyethylene dam fits 27in, 30in and 32in diameter manholes with an inflatable gasket that ensures a watertight seal.

Four outrigger support gussets stabilize the shield. Barrier walls are 12in tall to keep water and mud out of manhole as you work. Can be used with Allegro guard rail and shield retainers.

Guard rails sold separately.
