So, it's clear we need to do something to shield our mantels, but after thinking about how far an angled piece of metal has to stick out, I was wondering if anyone has ever put in a small piece of metal onto the mantle (permanently- probably screwed onto the lintel), and then temporarily clamped or screwed on a larger metal extension for the winter season. Then the extension could be removed when not needed during the warm months. This is about appearance primarily, but am also thinking the shield would be out of the path of traffic, avoiding snagging clothes, etc. Thanks.
