what type of UL do i need for conduit going through top track of stud ?

Hello Joe,

We do not have a UL system for a conduit going through the top track at a head of wall joint.  However, we could create a solution for you to use in the form of an engineering judgement.  This engineering judgement will be based off both penetration and joint UL systems that we have.  Please fill out the attached form and send to us at usfirestopeng@hilti.com.

Best Regards,
Cody
