This is the width of your hearth, please give the exact size and we will build in an appropriate plus tolerance.

This is the depth of your hearth, please give the exact size up to the front face of your skirting board or wall if no skirting is present.

This is the width of your mantle uprights at the relevant fender model seat height, so that we can position the seats so as not to interfere with them.

This is the depth of your mantle uprights (i.e. how far they protrude from the wall). This dimension is necessary if dimension C is close to being the same as dimension A and the seats need to finish short up against the front face of the mantle uprights.

This is the thickness of your skirting from the wall so that we can finish the base up to the skirting and the seats up to the wall.
