About this detail

A steel anchor post for a horizontal lifeline extends through a single-ply membrane roofing system and is welded to the structural steel beam below. The base plate rests on the structural framing, while the post penetrates a roof assembly consisting of metal deck, concrete fill, rigid insulation, and protection board. A flashing membrane extends up the post with a minimum 8-inch height and is secured at the top with a stainless steel draw band clamp over a continuous bead of compatible sealant. The flashing membrane is hot-air welded to the surrounding single-ply roof membrane.
