Is there anyway to run calcs on older anchors, specifically the KB TZ

I am looking for a 3hr rated edge of slab detail but I am abutting brick, stone, or CMU and not curtainwall.

Is it allowed to install Kwik Bolt TZ anchors at an angle into Concrete? If yes, what are the limits, and does it affect the capacity of the anchors?

what size sleeve do i need to install 2 1" EMT conduit

Can UL HW-D-0609 be used below steel tube beams (HSS)?

When Specifying ASTM F1554 Anchors the program will not calculate

We are using AER-09038 as a two hour horizontal assembly and need a firestop assembly for plumbing penetrations.

Is there a listing for this condition? I can only find WW-D-0067 which is for a joint between two metal stud walls, but it has no F or L rating. We are looking for one with a F and L rating.

Is there any other listing, other than WW-S-0059, with a F and L rating? I have exhausted my searches and cannot find one, but need it, WW-S-0059 is not accepted by the State Fire Life Safety Officer because of it. Options?

We have an existing wood truss building that we want to add a 3-hour fire barrier wall to keep the square footage down and avoid fire sprinkler the building. Going to be very hard to work between the truss webs so were trying to see if there is any type of 3 hour lid or intumescent paint that would provide that opportunity.
