Sealing around electrical and cable lines.

Ready. Aim. Done.


Holes made for threading wires through walls and studs leave lots of room for air to travel through a home. That much airflow does more than let temperature-controlled air sneak in and unwanted air leak out. If there’s ever a fire, these holes help fuel the spread of smoke and flames. GREAT STUFF PRO™ Gaps & Cracks is fireblock rated and fills those gaps, helping to impede the spread of smoke and flames.
