Yeah, the link I found was just the best I could be arsed looking for, we've got some rings that I found in a steel merchant, double bolted into the wall, with a securing plate on the other side. I put them in when removing a cole shute, you'd need to cut about 30mm of steel or remove several square feet of double layer structural brockwork.
