Roof Penetrations and Rigid Post Horizontal Lifelines

We’ve covered the advantages of tip over post technology in countless prior posts.  Assuming we aren’t dealing with a steep pitch application or thin gauge roofing material, a horizontal lifeline with tip over post technology will reduce shop fabrication and installation time, reducing costs.  More importantly, tip over post lifeline designs minimize roof penetrations which can cause leaks.  There are scenarios where an architect or engineer won’t deviate from a rigid post design—or instances where the pitch of the roof or gauge of the roof deck rules means a rigid post design is the only option.  That said, these installations require making large openings in the roof.  In case you are wondering just how large of an opening we are talking about, the pictures below tell the story.
