First Place Supply is proud to offer stackable manhole shields from Pelsue designed to protect workers and prevent accidents. A type of safety equipment, a manhole shield forms a protective ring around the manhole opening with a pneumatic seal around the base that you inflate with air or nitrogen to form a water-tight seal around the manhole.
Manhole shields are easy to use and work effectively to block ground water from entering manholes. to help protect workers from the danger of water entering confined spaces such as a sewage or stormwater drain, or a telecommunications or electrical conduit.
Manhole shields typically consist of an aluminum, metal, or plastic frame that fits around the circumference of the manhole opening, with a hinged or removable cover that allows access to the manhole.
Manhole shields also serve to protect the integrity of the underground utilities and services that they cover. In addition to keeping water out, they can help prevent damage to the manhole and the utilities within it and can also help prevent debris or other foreign objects from entering the manhole and causing problems.

FAQs
How is a manhole shield used?
Manhole shields are typically used when work is being performed near an opening in the ground, such as during utility maintenance or construction. The shield is placed around the manhole cover and inflated with air using a compressor or other pressurized air source. Once the shield is fully inflated, it creates a tight, airtight seal around the manhole cover, preventing the escape of gases or the infiltration of water or other fluids.
What safety precautions should be taken when using a manhole shield?
It is important to follow proper safety procedures when using a manhole shield to ensure the safety of workers. This may include: wearing personal protective equipment, such as hard hats, gloves, and safety glasses; ensuring that the shield is properly secured in place before beginning work; inspecting the shield for damage before each use; and following all local and national safety regulations and guidelines.
How does the Pelsue Manhole Shield work to keep water out?
A watertight seal is formed by the heavy-duty puncture resistant tube inflated with 25 to 35 pounds of air, or until the shield fits tight in the manhole. It is important to inflate the tube only when the shield is in the manhole to avoid injury.
Does the Pelsue Manhole Shield require clamps?
There are no clamps to adjust and no sealing compound to apply or remove.
