[Double Venom]

Man this is a great place, now we're even getting international guidelines! Problem with that info does not indicate what material the mounting substance is or needs to be!
If you thought that it would be 'legal' to fasten as shown and your floor is fiberglass- me thinks/knows it would fail.

But great stuff, I'm not sure if the U.S. even has guidelines like that? Somebody tell me I'm wrong...AND NSRA rules ARE only suggestions, they are not legislative rules/guidelines!
