600 x 450mm Sealed & Locking Recessed Manhole Cover

The 600 x 450mm sealed and locking recessed manhole cover is designed for installations where improved sealing performance is required over a standard recessed tray. It combines a galvanised steel tray with a polypropylene frame, providing a durable and corrosion resistant access solution.

This cover is typically used in internal environments such as kitchens, utility rooms and basements, where drainage odours need to be contained. The factory fitted rubber gasket works in combination with the screw locking system to compress the lid onto the frame, reducing the risk of odours escaping into occupied spaces.

It can also be used externally in pedestrian areas such as patios, where it helps limit debris and surface water entering the chamber. It is not suitable for trafficked areas due to its 5 tonne load rating.

Incorrect specification often occurs where a non-sealed cover is used internally. This design addresses that by combining a defined clear opening size with a sealing system, ensuring a consistent fit and improved performance in service.

• 600 x 450mm clear opening suits standard rectangular inspection chambers
• Rubber gasket seal helps prevent odours escaping in internal installations
• Four screw locking system secures the cover and improves sealing performance
• Recessed tray accepts concrete or screed for a flush floor finish
• 5 tonne load rating suitable for pedestrian areas and light external use
• Polypropylene frame resists corrosion in damp or ground conditions
• Integrated lifting handles allow safe removal without separate keys
• Moulded grouting flange helps secure the frame during installation

The tray is manufactured from galvanised mild steel, providing strength and resistance to general corrosion. The frame is made from polypropylene, which is lightweight, non-corrosive and stable in damp environments. This combination balances durability with manageable handling weight.
