The R23 replacement door and frame is designed to repair the through-the-wall gas meter box.

Although this is a fairly unusual box,  these boxes still have GRP doors and are just as susceptible to damage as any other. So Ritherdon have designed the R23 door and frame to repair them.

If you are unsure if the R23 is the correct repair unit for your meter box look for a meter box that allows you to read the meter from the inside or the outside of the property. This fairly unusual box is effectively a plastic tube through the wall of a property, allowing the meter to be easily read from the inside or the outside.
