The grate in my fireplace has a hugh hole in the middle. When I went to look for one to replace it I could only find ones that were wedge shaped (narrower at the back than at the front), not square shaped like I need. Any idea where I can get one to fit?
I remember having the same problem a few years back - I didn't have to look very far in the end though.
Have you tried traditional, family owned, high street hardware places as opposed to the big supermarket type outlets?
I got ours in somewhere like this. Take the measurements of your old grate and try a place like this if you can.
