What is a 900 x 900 manhole cover?
Whether referred to as a manhole, access, chamber or drain cover, 900 x 900mm (35.4 x 35.4”) covers are one of the bigger off-the-shelf covers we make. These shallow square covers are often found on some domestic installations and more so in commercial settings in a variety of materials including steel, cast iron and sometimes plastic.
Calculating the correct size
Manhole cover sizes and their frames are determined by their clear opening size - referring to the size of the chamber opening (brickwork to brickwork) which the cover is to span over.
If you can lift the existing access cover you have on site and the measurement is in the region of 900mm (+ or - 30mm) then you will need a 900mm opening cover and this section of the website has your cover options. If the overall size for your cover is in the region of 1m then equally you will most likely need a 900mm opening cover. It is always best to lift the old lid and measure the actual hole size.
Spotlight: Aluminium 900 x 900 recessed drain covers
Our twin-tray 900x900mm cover is one of the most popular covers in this size. The EG9090/100 is 100mm deep and can take infill including grass, gravel, blocks, or flags. It can take 120 tonnes of weight over it.
This cover is designed with twin trays so when lifting the manhole lid it can be done so easier. If we produced this with a single tray it would be hard to lift due to the infill weight.
We also have a 43.5mm deep version of this cover for applications where the cover infill is shallower. We would advise this cover for tiles, vinyl or flag infill.
