I have this detail that states only 2 Tstat wires can pass through a ceiling penetration. Because the linesets follow the tstat line this means that I can only have two line sets / tstat lines penetrate through ceilings. Is there a detail out there that allows more penetrations through a ceiling in this case?

Looking at what is and is not accepted by PE boards for renew of licenses and I'm not sure about the Hilti PDH credits. I look on you site and could not find an explanation on this topic.

Can Hilti concrete screws 3/4 diameter be used in concrete lower than 2,500 psi. You have a custom button... please advise. I have 950 psi strength.

Looking to see if webinar documents are available.

I spoke with a representative from Hilti over the phone, and they said that there’s no mention in the specs about incompatibility with Intumescent paint. They recommended I reach out to you for confirmation. Could you confirm whether it can be used or not? Thank you!

The EJ shows a firestop joint spray overlapping or lapping up concrete surfaces, but the note says the joint spray should overlap adjacent surfaces. The construction joint terminates at the edge of the building and there is a...

I am working on electrical distribution for a building that requires me to penetrate a 3hr concrete slab between the First and Second floor with (6) 4/C 600KCMIL cables and (2) 4/C 350KCMIL cables. Is there a multi-penetration system I could use to provide a 3 hour rating for the MC cables or a single penetration system for MC...
