Agreed - the question is how? The original metal ones had screw holes,
and that style was what I wanted to replace them with, but only the
highest end fancy scroll pattern ones seem to available in steel these
days, at least where I shop. These appear to be thick, but it's mostly
air with a few ribs under the top surface - if I run screws through the
top I;ll just be setting up for cracks and breakage. I suppose I could
make some sort of clip. I don't think glue can be made to work.
