When I bought my home it was equipped with an outside steel door which measured approx. 24"X24". It was a completely enclosed system mounted on a steel box with hinges and had welded sides attached to it. It was used for coal delivery in the 30s, 40s, 50s right up until the home was converted to oil fired hot water which replaced the coal. The bin is still intact and I'm considering converting back to coal....no surprise there when anticipating $6/gal for oil.
Does anyone know of a manufacturer of such a steel door? Mine was rusted out and removed a few years ago and the opening in the concrete foundation was blocked in. Any help or suggestions will be greatly appreciated.
