I'm installing two 8x8x6'8 columns in my house to support a beam crossing a 16 foot span. These columns are HB&G square columns http://www.hbgcolumns.com/squarecolumns.html but what i want to know is that if i can cut in a box into the material without ruining the bearing load capacity... and i know a wire is supposed to be secured within 12 inches of a plug, but forgoe that thought right now please... hehe.
i was thinking if i use a Die grinding wheel and just install remodel boxes, i'll be all set. but if anyone has come across this anytime please drop me a line...
I think the only one who can answer this is the maker of the columns.

I don't know about a "plug", but in new work yes, the rule general is secure within 12" of a box.
If the cable is fished into a finished space then no securing is required. As with most, the box MUST have a clamp of some sort though. The molded in clamps in PVC boxes are fine.
Fishing down a column does fit this description.
Sometimes I feel like if I answer any more questions it is like someone trying to climb over a fence to jump off a bridge and me giving them a boost.

I have an email out to some of their ppl to see if i can cut a hole in them. But no response yet. You figured they'd be waiting anxiously at their desks on a Sat morning to receive an email... but who knows...
