Hepworth Plastic Manhole Cover

The Hepworth plastic manhole cover is a high-visibility safety cone designed to cover exposed manholes during temporary works. Fitting both 600 x 600mm and 675 x 675mm square openings, it’s built to reduce on-site risks and signal live manhole zones clearly to workers and pedestrians.

Made from durable polypropylene, the temporary hole cover is lightweight and stackable, allowing fast deployment across multiple zones. The yellow finish and elevated profile ensure it stands out across urban and high-traffic sites.

• Temporary site safety - Ideal for highlighting manholes during maintenance and groundwork.
• Durable plastic design - Polypropylene body resists weather and damage.
• Highly visible cone shape - Enhances visual alert for workers and visitors.
• Fits multiple openings - Suits both 600mm and 675mm manhole sizes.
• Specified on major projects - Recognised as best practice by safety bodies.

Temporary manhole covers play a crucial role in site safety, particularly in urban developments, utility upgrades, and roadworks. The Hepworth high-visibility manhole cover is engineered to ensure every open access point is clearly marked and effectively protected, minimising the risk of falls or trip hazards around unfinished manholes.

Used by infrastructure contractors and roadwork crews, it provides a physical and visual barrier over manhole openings while works are ongoing or paused. Its polypropylene body is weather-resistant and does not degrade from repeated outdoor exposure, ensuring long-term use over weeks of development.

At just 1050mm tall and 770mm wide, this manhole blocker fits over most standard square access covers and provides instant impact with its vivid yellow colour. The flared cone structure discourages approach, making it effective even in busy or low-visibility conditions.

Suitable for a range of manhole applications, including telecoms, drainage, or electrical access points, the temporary hole cover helps maintain HSE compliance and operational continuity. The design is supported by major UK schemes such as the Considerate Constructors Scheme and is regularly specified across key projects. It ensures a more secure and professional working environment for your teams and the general public.
