600 x 450 recessed manhole covers

Also referred to as access or chamber covers, our 600x450mm (23.6" x 17.7”) opening manhole covers are the most popular manhole size in the UK market. These rectangular covers are the most common size and are found on properties in a variety of materials including steel, cast iron and sometimes a plastic manhole cover.

Please note, manhole cover sizes and their frames are determined by their clear opening size - this is essentially referring to the size of the chamber opening (brickwork to brickwork) which the cover is to span over.

 

Is 600mm x 450mm the correct size for me?

To check if this is the right size for you lift your old chamber lid and measure the internal opening; if this opening is 600 x 450mm or close to that (+ or – 25mm) then you have the correct cover.

While determining the correct cover, you need to consider if the cover is internal and needs to be a sealed and locking or a double sealed unit. Also, the depth or recess you need or if a solid top is preferred, and also consider the traffic that will be going over the cover. After choosing these points it is all down to a choice of aesthetics and how you want the cover to look when installed.


Spotlight: Aluminium 600x450 recessed drain covers

One of our most popular options for external use is our Alusthetic double sealed aluminium manhole cover. It has a decorative finish to the edging, is sealed to prevent odours, and can withstand car traffic going over it.

If instead your application is indoors we have a triple sealed version of this cover which has three neoprene seals and locks down, so you can be 100% assured it will prevent odours and fully comply with building regulations for internal manhole covers.

With both of these covers we offer differing depths depending on your chosen infill; for thin tiles we would use a 40mm overall depth, for thicker tiles or flags we would use the 60mm overall depth, and for blocks we would use the 80mm deep option.
