Allegro Industries offers a complete line of work equipment for use in confined spaces.
Allegro offers the 12" High Impact Polymer Manhole Shield which surrounds a manhole opening to protect workers from street level water and mud that can flow into the work area. The inflatable shield ensures a watertight seal and fits 28”, 30” and 32” openings. Constructed of rugged, lightweight Polyethylene in bright yellow that resists fading, the manhole shield is designed with 4-outrigger support gussets that stabilize the shield. This unit can be used with the Allegro guard rail, tent, umbrellas or winch.
