Newbie- Help with support beam question
Hello everyone
I have a rookie question. I live in a two story house with the second story sitting above my garage. Theres a huge beam going across my garage that supports the second story. I want to install a simple pull up bar using black pipe and floor flanges. My question is... Can i screw 4 inch lag screws into the beam either through the bottom or the side to install the pull up bar? Im wondering if making 8- 5/16 inch holes will compromise its structural integrity. Thank you for your help.

Technically speaking, holes should not be placed in the middle 1/3 of the span of the beam. The outer 1/3 would be okay. So if you wanted to play it safe, the outer 1/3 would be best. That way the holes and your additional weight would not put additional stress on the middle of the beam.
