2hr Fire Stop for multiple 1/2" MC cables
We have a condition where we have up to 40 1/2" MC cables that need to penetrate a 2-hr wall. Typically they are grouped together into "bundles" of 5. What firestop system would work for this? There are also 4 pipes that are penetrating the wall in the same area, and so I don't know if it would be better to have one large firestop sytem.

Hello,
I have attached a couple systems that may work for you here. They might not though depending on opening size and annular spaces. Please submit for an engineering judgement on the link below with your specific opening details if these do not work and we can work on a solution.
