RE: [TCML] Safety Gap Construction

["Lau, Gary" <Gary.Lau@xxxxxx>]

For use in a safety gap that fires only infrequently, this is not an issue.  But be advised that brass-plated acorn nuts are often sold.  I purchased some for RSG electrodes, and the plating rapidly eroded, exposing a soft base metal, which also eroded quickly.  If it matters in your application, bring a file to test.
