The BO is only trying to do his job. If he doesn't have the experience or knowledge to determine that the extra weight of your trapeze can be handled by the bottom chord, then he should have asked you to get your permission slip from the engineer or remove the rack. We teach that trusses are designed to carry the weight on the top truss. This BO apparently took that as meaning all weight, no matter how light, would have to be from the top. In time, this BO will understand that small weights can be supported from the bottom. Until then, get the engineer to write you up an OK.
