3M™ Fire Barrier Putty Sleeve Kit

3M™ Fire Barrier Putty Sleeve Kits  are designed to help prevent the passage of fire and smoke in new or existing cable penetrations through walls or floors. Each kit comes complete in a box containing a 3M™ Fire Barrier Putty Sleeve (two-part metallic sleeve with a set of two-part metallic flanges), 3M™ Fire Barrier Mouldable Putty, sheet metal screws, drywall screws and two installation identification labels.
