We have organized several common questions for our clients，may 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. The project I’m working on requires a manhole cover with a quality finish, what’s available?
A. Naturally, galvanised steel of black polypropylene aren’t always ideal, and so we offer brass or stainless steel edging, as well as complete stainless steel covers.
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.
