Hello, I am looking for a Firestopping detail for a 3x3x 5/16 steel angle iron penetration through a fire rated wall. Please see attached detail. The iron is a 45-degree kicker. The only systems I managed to find only cover 2x2. May you please help?
Greetings Nick,
Thank you for using ASK Hilti!
Our systems W-L-7130 and W-J-7123 both callout a
maximum of 2” x 2” x 1/8” thick angle. We unfortunately, do not currently have
a tested and listed system to allow for this size you are looking for. However,
we can most likely support your situation through an engineering judgement
based on opening size and annular space requirements. Feel free to submit for an
engineering judgment request through www.hilti.com/EJ
and we will be happy to work with you on a custom detail.
If you have any questions firestop related,
please reach out to our customer service team at 1-800-879-8000 (US) or
1-800-363-4458 (Canada) and ask to speak to the firestop team for assistance.
We would be happy to walk you through the details of any firestopping Hilti
UL/cUL listed systems you needed.
Thank you for choosing Hilti as your firestop experts!
