Unlike pry bars or multi-piece lifting systems, the 9401-20 is a single-piece tool that requires no assembly and stores compactly with the hook locked into the pole. The combination of a 42-inch all-steel handle, a 6-inch angled support leg, and a heat-treated alloy steel hook rated to 6,000 Kgf-cm of max torque gives it a mechanical advantage that reduces physical strain compared to improvised lifting methods. Cadmium plating and rubber components address the corrosion and slip hazards common in sewer and utility environments.
Key Features & Benefits
Long All-Steel Handle with Angled Support Leg
The 42-inch all-steel handle combined with a 6-inch angled support leg provides the mechanical leverage needed to remove and replace even the heaviest manhole covers. This reduces the physical effort required and minimizes strain on the operator during repeated lifts throughout a workday.
21-Inch Heat-Treated Alloy Steel Hook
The hook is constructed from alloy steel that has been heat treated for added strength, allowing it to handle the demanding torque loads encountered when breaking loose stuck or debris-laden manhole covers. At 21 inches, it provides deep, secure engagement with the lid.
Hardened Cadmium-Plated Finish
The cadmium plating on the hook is hardened to resist rust and corrosion, which is critical for tools regularly exposed to sewer gases, moisture, and road chemicals. This extends the service life of the tool and reduces replacement costs over time.
Lockable Hook for Safe Storage
The alloy steel hook recesses and locks into the pole when not in use, eliminating the risk of accidental deployment during transport or storage. This makes the tool safer to carry in a work vehicle alongside other equipment.
Rubber Grip and Rubber Foot
Rubber grips on the handle provide a secure, non-slip hold during lifting operations, while the rubber foot minimizes slippage on pavement or wet surfaces. Both features contribute to safer operation in the field conditions typical of utility and sewer work.
Common Applications
Utility Maintenance
Used by utility crews to access underground infrastructure for inspection, repair, and maintenance of water, gas, and electrical systems beneath manhole covers.
Sewer and Wastewater Operations
Provides reliable lid removal for sewer maintenance crews entering confined spaces for cleaning, inspection, or emergency response in wet, corrosive environments.
Construction Site Access
Enables construction teams to quickly open and close manhole covers during underground utility installation or modification work on active job sites.
Confined Space Entry
Supports confined space entry programs by providing a controlled, safe method of opening manhole lids prior to atmospheric testing and worker entry.
Compatible Materials
- Cast iron manhole covers
- Steel manhole covers
- Heavy utility access lids
