  1. What is the purpose of 3M™ Fire Barrier Pass-Through Device Foam Plugs?

    The main purpose of these foam plugs is to maintain the integrity of fire-rated walls and floors where cables, pipes, or conduits penetrate through.

  2. How does it work?

    When exposed to high temperatures during a fire, the foam expands and creates an effective seal around any penetrants. This helps prevent smoke and toxic gases from entering adjacent spaces.

  3. Is this product easy to install?

    Absolutely! The foam plugs are pre-scored for easy-to-customize fitting around various cables sizes. They also require no special tools or adhesives for installation, just simply insert them into each opening until they fit snugly against both sides of wall/floor assemblies.
