Hey any of you Gents know when the code for guardrails changed to allow max 4" spacing?

Without looking it up I am not certain, but I believe it was in the late 1980s.

Marc,

I specifically find the 4" rule in the 1997 UBC (509.3). I seem to recall it first appeared in the 1991 UBC. Unfortunately, I do not have my earlier codes available at present. Of course, you need to remember that CA did not enforce the 1991 UBC until 1994.

Therefore...

Excellent Gunnar, much appreciated brother!

I have CABO requiring 4" in 1995 and IRC in 2000.

I know you are not in a state that used the BOCA code, by 87 BOCA says 6" and 90 BOCA says 4". 86 CABO says 6" and 92 CABO says 4".

If you want specifics you should do some research.

Really? What are you my mom?
Seems like everyone else was pretty cool about answering the question and nobody else had any problems with helping out. And, they did it without stupid ass comments like yours. Next time don't reply if you can help yourself.
