B, is my vote.
No longer in the model codesDwightB said:...isn't there also a restriction against the ladder configuration?
Ladder effect wording was only in the 2000 IRC and was removed in the 2001 IRC sup. I was never in any other ICC Model code.DwightB said:I just ran across this thread. It answers many questions that I've had about cable rail systems and spacing relative to the minimum sphere as mentioned in detail several times here. On another point though, I thought there was also some requirement that railings must not be horizontal and thus easy to climb because of the ladder effect. I see a lot of railings now with closely spaced vertical bars that would easily comply. Following this discussion, I am now convinced that cable systems can meet the sphere test, but isn't there also a restriction against the ladder configuration?
I have to disagree, the code has nothing to do with getting stuck, if they get stuck the guard did it's job.ADAguy said:To further expand this issue:1. Force applied is not identified as static vs dynamic (as in when runs into or is pushed into the railing and its ballistars)
2. 4" is intended to protect little ones from getting their heads stuck no mater what the drop off height (best practice vs performance requirement?) If greater than 4" clear space who wins in court if dropoff is less than 30"?
