Is there a TZ or KB3 anchor certificate

Hello, Can the Hilti CP617 or CFS-P PA firestop putty pad be used as an opening protection material for an enclosure flush-mounted in a rated ceiling? Enclosure dimensions: 5.0”H x 17.9”W x 17.9”D. See attached cutsheet of the proposed enclosure to be mounted in a 1 or 2 hr rated ceiling. If not, does Hilti have a product ...

Attached are photos of ceiling beams on the 4th floor hall way. The electricians ran these wires for common space outlets in the interstitial space. Is this a code violation? Can I leave the wire and if need be just simply fire caulk any penetrations?

Why is the Hilti Profis design calculation title grayed out and unable to be edited? I created a anchoring to concrete design in a company project and once the calc is created the name is locked. I need to be able to edit design names.

Where is warranty information for firestop materials?

Due to overzealous drilling we must move some anchorage locations but it will result in the minimum spacing between bars to be less than Hilti recommendations. I would like to discuss this with someone....

What PAF fasteners does HILTI recommend to anchor 2x lumber to structural steel.

There are some room in the project which are pressurized room, the partition wall can withstand the 500 Pa, the question is HILTI firestop product (FS ONE MAX and CP660 or others) can withstand the 500 Pa pressure?
