I would have took this installation if he had put the joint below the first strap, used a rigid coupling between the straps or guy'd the riser off. maybe not 100% code compliant but I would feel a resonable level of safety had been accomplished. I am most concerned with the strength of the riser. This is a 109' pull here. As for the straps, we call them stand off's or thru wall bolt clamps. They have a bolt that goes thru the wall and are required by the poco. This guy calls when things do not go his way, you guys know the type. This is 2 1/2" RMC or IMC.
