I see the part in the rules where it says the rear down bars have to be welded to the hoop.
What I don't see is anything saying they must be one continuous piece of tubing. Make it bolt together say a foot from the hoop and carry the rule book with you. Done right it may be the strongest part of the cage. For sure it will be stronger than front swing out bars.


In theory, there is no difference between theory and practice. In practice, there is.
