5FAQ:

We have organized several common questions for our clientsmay help you sincerely

Q. Can I fit a square manhole cover into a round chamber?

A. Yes, there are a select few manhole covers which are square-to-round, meaning they will fit square or round chambers. 

Q. I have a heavy traffic manhole cover but it has been broken by a forklift, why?

A. Forklifts have solid wheels which apply pressure differently to standard pneumatics and therefore covers must be specially adapted to suit this.

Q. I’ve measured my clear opening size but none of your covers match it, can you offer anything?

A. It’s likely that your cover is quite old and in imperial measurements which are no longer manufactured. However, we can offer bespoke solutions with manhole covers made to the specification you require.

Q. Odours are coming through where I have installed my manhole cover, why?

A. Your cover must be sealed and locked, or neoprene sealed, so you would require a T-Range Cover, or if you require a solid top, a selection of the PC range (e.g. PC2BG3, PC6CG3, not PC2BG) are suitable.

Q. I need access through my manhole cover on a regular basis, is this possible?

A. Yes, the majority of covers have built-in lifting keys, and for those that don’t we also supply lifting keys. However, the best way to obtain easy access is to have a bespoke, hinged manhole cover.
