Simplifying How Doers Get Equipped!
Manholes are the entry points to underground utility systems, for maintenance workers and technicians to access sewer lines, storm drains and other critical infrastructure components. The manhole is more than just a hole – it’s a critical access point for inspection, maintenance and connection within utility systems. This section has a range of tools and equipment for safe and efficient operation of manholes. Some products are based on actual sewer systems to show how manholes work in practice. Learn more about manholes and related equipment.
From manhole cover lifters to specialized hooks and steps, these products are built to last and function. Drain grate lifters come in various sizes and styles to fit different types of covers, while manhole hooks provide a secure grip for lifting heavy lids. Drain grate lifters and manhole cover openers are available for different diameters and sizes, including square and rectangular covers. Top popper manhole cover openers are a convenient way to access manholes without having to use excessive force or risk of injury.
For added safety and ease of use, manhole steps are available in different configurations to suit various installation requirements. Single and double face steps provide a stable footing for workers entering and exiting manholes, while lift-eye pin inserts provide a secure mounting point for lifting equipment. The selection of steps and accessories can be tailored to the specific details and requirements of each project.
Whether you are a contractor, utility professionals or municipality looking to maintain underground infrastructure, this section of manhole tools and equipment has you covered. Choosing the right tools will save you money in the long run. Invest in quality products to ensure smooth and safe operation of manholes for years to come.

Manholes, also known as maintenance holes or sewer access points, are a critical part of any sewer network. They provide access to underground sewer pipes so maintenance crews can inspect, monitor and clean the system. The main purpose of manholes is to allow workers to maintain the flow in the sewer, prevent blockages and keep the network healthy. Manholes are usually installed at regular intervals along gravity sewer mains, especially where there are changes in direction, slope or elevation. In most cases the manhole covers are set flush with the ground surface so maintenance teams can easily find and access them. The sewer industry relies on these access points to keep pipes in optimal condition, for timely inspection and cleaning and for the smooth operation of the entire sewer system.
A manhole is made up of several key components, each designed for safe and efficient maintenance. The manhole cover, often made of durable cast iron or reinforced concrete, sits within a steel or concrete frame at the surface, creating a tight seal to prevent odors and water infiltration. Beneath the cover the shaft or chamber leads down to the base of the manhole, providing space for professionals to enter and inspect. At the bottom the bench provides a stable surface for professionals, while the channel directs the flow of wastewater through the manhole, for smooth passage between connected pipes. Many manholes also have ladder rungs or step irons inside, to make it easier and safer for professionals to descend for maintenance or inspection tasks. Each of these components is critical to the integrity and functionality of the sewer system.
Building a manhole involves installing precast concrete sections into an excavated hole, with the round shape preferred for its hydraulic efficiency and structural strength. The concrete used is usually type I or II cement, chosen for its durability and long life. Manholes are available in standard sizes to fit most projects but can be custom built to meet unique requirements. In some cases manholes are built with special features such as sealed joints or protective coatings to address site specific conditions or industry needs. High quality materials like steel and concrete ensure manholes can withstand the demands of the sewer industry, providing reliable access points for maintenance and inspection. Proper construction is key to the performance and longevity of the sewer network.
The location and placement of manholes is key to sewer maintenance and inspection. Manholes are usually installed at points where sewer pipes change direction, slope or elevation, so professionals can access the network at regular intervals. They are also found at the intersections of sewer branches, providing convenient access points for maintenance crews. The type of sewer system – sanitary or storm – can influence how often manholes are installed, with more access points required for higher volume systems. In most cases manholes are located in roadways, on private property or wherever sewer pipes are present, so professionals can easily reach and service the network. Proper planning of manhole placement maximizes coverage and efficiency of the entire sewer system.
Safety is paramount in manhole design with several features built in to protect professionals and the public. The manhole cover is a critical safety component, designed to prevent accidental falls and unauthorized access while providing a secure seal against surface water and debris. Inside the manhole ladder rungs or step irons are often installed to help professionals safely enter and exit during maintenance or inspection. Some manholes have additional safety features such as confined space entry equipment or ventilation systems to reduce the risk of exposure to hazardous gases. Regular inspection and maintenance of these safety features is essential to ensure manholes remain safe for professionals who need to access the pipes below.
Manholes provide access points for crews to reach pipes, remove blockages and assess the condition of the system. Regular inspection allows professionals to monitor the flow of wastewater, identify potential issues and address them before they become costly repairs. The frequency depends on the type of system and age of the pipes, with sanitary sewers requiring more frequent attention. In most cases specialized equipment such as hydro jetting machines or CCTV cameras are used to inspect and clean the pipes. By providing access to the sewer network manholes play a crucial role in preventing blockages, reducing costs and ensuring the long term health of the system.
