320mm Recessed Manhole Cover & Frame 46mm deep

Product Description

This 320mm Recessed Manhole Cover & Frame 46mm deep, with a 46mm deep tray, provides a neat, flush, and secure access point for underground drainage or inspection chambers. Ideal for installations where paved surfaces, screed or concrete finishes need to sit level over the cover, it allows surrounding materials to overlay the frame, resulting in a clean, integrated look without protruding edges.

Constructed with a square frame and a circular opening in the centre, this unit uses durable materials: a black polypropylene frame allied with a galvanised steel recessed lid. A rubber gasket seal ensures water-tightness, while four locking screws help secure the cover firmly in place. The whole construction is built to resist weather, soil pressure, light pedestrian or driveway loads (depending on use), and regular access.

With a tray depth of approximately 46mm, the frame provides enough recess to accommodate overlay finishes — paving, screed, tiles or setts — so the top of the cover sits flush or nearly flush with the surrounding surface. The square outer frame dimensions give a tidy border around the circular lid, balancing aesthetic appeal and functional access.

Key Features

• Square frame with circular lid opening — square outer, round inner access.

• Overall size: 320mm × 320mm frame; tray depth ≈46mm.

• Materials: galvanised steel lid; black polypropylene frame; rubber gasket seal; locking by 4 screws.

• Designed for recessed installations — suitable for concrete or screed infill and flush surfacing.

Benefits

• Aesthetic integration: Recessed design ensures surrounding surface finishes like tiles or paving can sit flush over the frame, producing a clean, professional finish without raised edges.

• Secure and watertight: Rubber gasket + locking screws help prevent water ingress, debris buildup, or cover movement — important for maintaining drainage integrity.

• Safe and stable: 46mm tray depth gives enough embedment without excessive box build-up; reduces trip hazards and keeps cover secure under foot traffic.

• Durable materials: The combination of galvanised steel lid and polypropylene frame resists corrosion, environmental wear and underground stress.

• Low maintenance access: The lid can be unlocked and removed for inspection or cleaning, without disturbing surrounding finish or having to lift large heavy lids unnecessarily.
