Kirby, if you do a simple, max. transverse cornering force at the top of the
strut analysis, you will find that a column of 1/2" EMT is adequate for the
job. Column failure will occur long before compression failure.
If you read the disclosure, you will realize that the brace is designed to
be always in compression, which has several functional advantages, besides
cost. The alignment procedure must be adapted to insure that this be the
