Therwen 36in Manhole Cover Hook - Heavy Duty Lid Lifter

In this review the Therwen 36in manhole cover hook is evaluated for utility workers, maintenance crews and homeowners who need a reliable, no-nonsense tool for lifting sewer grates, septic covers and other heavy lids. The single biggest reason to buy it is its simple, heat-treated 5/8in hex alloy steel construction combined with an oversized D handle that makes stubborn lids easier and safer to lift without improvised tools. It is a straightforward, visible and durable lifter built for repeated use on job sites where leverage and hand protection matter.

Key Features

• Versatile Hook Design: The single hook end doubles as a general lifting tool, allowing users to open steel grates, lift septic tank covers and move machinery with one implement.
• Sturdy Alloy Steel: Made from corrosion-resistant 5/8in hexagonal alloy steel and heat treated, the shaft resists bending and delivers dependable strength under load.
• Enhanced Handle: The oversized D-shaped handle fits gloved hands comfortably and the blue finish improves visibility on busy worksites.
• Optimized Leverage: Pivot-style heads provide extra leverage so lids can be lifted with less strain and reduced risk of injury compared with improvised pry bars.
• Multipurpose Utility: Beyond manholes, it can aid in pallet pulling and other material handling tasks in warehouses and yards.

Who It's For

The Therwen 36in hook is a practical choice for municipal workers, landscapers, plumbers, and facility maintenance teams who frequently need to lift grates, manhole covers or septic risers. Its visible color and rugged build make it well suited to outdoor and industrial environments where a durable hand tool is essential.

It is less appropriate for precision work where a smaller pry tool or specialized lifting apparatus is required, and it is not a substitute for mechanical lifting equipment when handling extremely heavy or awkward loads that exceed safe manual capacity.

Pros & Cons

Pros

• Durable, heat-treated 5/8in hex alloy steel shaft provides reliable strength and resistance to bending.
• Oversized D handle improves grip while wearing gloves and the blue finish aids quick identification.
• Pivot heads and pointed forged tip increase leverage and ease penetrating small recesses.

Cons

• Manual tool only - not suitable for very heavy covers that require mechanical lifting equipment.
• Pointed tip requires care and safe storage to prevent accidental injury.

Specifications

Our Verdict

The Therwen 36in manhole cover hook is a solid, value-oriented tool for anyone who needs dependable manual lifting of grates, septic covers and similar lids. Its heat-treated alloy shaft and large D handle mean fewer surprises on the job, and the visible blue finish helps keep it from getting lost. Buy it if you need a rugged, multipurpose lifter for routine maintenance and material handling tasks; do not expect it to replace powered lifting equipment for very heavy covers.
