No need to be 'sorry'! A few of the posters that commented on this are not very active. That said....comments from the 'new' members are always welcomed.

That sure is a lot of embarsassing work right there.


I would rather beg for forgiveness then beg for permission.

The documentation I have read on several manufacturers of TGI's claim a round hole up to 1 1/2" can be made anywhere in the web as long as you stay 24" away from either end and provide 2 diameters (largest hole) of space between holes.

Larger holes must follow a chart that tells you how far from the center of the beam you can drill given the size of the hole you need.

I almost never hammer out the knockouts because they blow out bad on the backside and they never line up for a smooth pull.

The LVL's can be drilled too but with much less freedom. I prefer to go around those if I can.

Just looked up LP's chart and it's a bit different from the last one I referenced.
