[MRCA] OT: corners to protect a table?

[W2HX]

In this photo of my operating exploits this past weekend, you can see a
military table I am using to operate. I was wondering if anyone could point
me to a supplier of "protective corners" little metal parts that can be
nailed to each of the 4 corners of this table to protect them?  It seems
that every time I move the table, more of the corners gets chipped away.
