Ready to Install and Prepared to Protect
Prevent the passage of fire and smoke with 3M™ Fire Barrier Putty Sleeve Kits. These fire barrier sleeve kits can protect existing cable penetrations through walls or floors and be used as a one-piece sleeve or the sleeve may be split/hinged for existing cable installations. Tested up to 4 hours for fire-rated through penetration systems in accordance with ASTM E814 (UL 1479), these putty sleeve kits are a ready-to-install kit. This product does not require gaskets and its rolled-out lip on sleeve facilitates smooth cable entry. The sleeves can be easily installed in openings that are either tight to the sleeve or irregular and can accommodate oversized openings (up to a one-inch larger diameter than the 3M™ Fire Barrier Putty Sleeve diameter).
3M™ Fire Barrier Putty Sleeve Kits are suitable for installation in gypsum wallboard and concrete walls or floors and ideal for applications such as:
Existing through-penetration openings with cables
Future cable installations
New construction through-penetration openings for power and communication cables
Versatile Kit for an All-in-One Solution
3M™ Fire Barrier Putty Sleeve Kits are ideal for high traffic cable penetrations and designed to be used for both new construction and retrofitting. The blank sleeve (0% cable fill) accommodates future cable installation while the two-piece split/hinged design offers easy retrofit installation on existing cables. The brackets and sleeve work in tandem to help prevent slipping during installation so the sleeve will remain in place.
Each kit comes complete in a box containing a 3M™ Fire Barrier Putty Sleeve (two-part metallic sleeve with set of two-part metallic flanges), 3M™ Fire Barrier Moldable Putty+, sheet metal screws, drywall screws and two installation identification labels. These kits can be used as a one-piece sleeve or the sleeve may be split/ hinged for existing cable installations. A versatile and economical solution, these putty sleeve kits are able to meet application requirements in such a way that help reduce inventory.
