Manhole Cover Loadings

Manhole Covers

All manhole covers, regardless of the manufacturer, are measured by the clear opening size. For example, if you have measured your broken cover as being 26" x 20”, you will need a 600mm x 450mm manhole cover (24” x 18”). Unless your broken cover is relatively new it is very unlikely that a new cover will fit your old frame – you will be much better advised to break out the old frame and fit the new frame that comes with our cover. It will be much stronger and safer and will last much longer. The only additional items you are likely to need for this job are a spirit level and a small bag of sand and cement.

Please note, we only supply manhole covers in the sizes listed - we are unable to supply made to measure sizes.
