Sleeve Through Fire Wall

[NorthwestPV]

We need to install sleeves through a firewall for data and communications. Is there a distance that the sleeve must extend past the wall on each side?

Dont think so. STI and other companies make sleeve kits, and they only extend a few inches at most from either side. Here's a pic of an install I did years ago:

iirc, some firestops arent rated for cable bundles, so make sure you use the right stuff. I believe the cable in the pic has Hilti FS-1 in it.
