Thanks Steve.
I found some HILTI HDI-P & HDI-P TZ that are both listed and have
specific criteria for the hollow core panels. That's what the
contractor wants to use, so I'm going with that.

Once upon a time, when Span Crete was a precast plank of choice in the
markets we served, we used “mollies” i.e. butterfly nuts that we
pushed into the cores. Worked like a charm and you could double nut
from below and/or deadhead the rod against the underside of the
interior cell, which made it more stable for loading pipe into the rings.
I have no idea if this is considered an acceptable practice now,

*Subject:* [Sprinklerforum] Concrete Hollow Core Hanger
I have a project with concrete hollow core panels. It is a cold room
with a dry system. The mains are 6".
Does anyone have suggestions on which concrete insert or screw that
will work for these?
