Does anyone know who make 2-hour fire rated wire way or pull box? Tks

If you look at UL listing for Metallic Outlet Boxes (QCIT), it seems that any listed metal box can acheive a 2-hour rating when installed in accordance with that listing.

Anbm,

The problem is that as per building code you are limited to a membrane penetration of 16 square inches per opening.

You can always try to get the two hour wall built around (and behind) the box or wireway.

Raider is good with the building code, maybe he will chime in.

Local code around here requires you to wrap the outside of the box with 2 hour fire rated puddy pads.
