3M™ Fire Barrier Moldable Putty Stix MP+, 1.4 in x 11 in

Manufacturer: 3M
Product Description

3M Fire Barrier Moldable Putty Stix MP+ is designed to firestop a wide variety of through penetrations, including cable, conduit, insulated pipe and metal pipe.

The Moldable Putty Stix is a one-part, ready-to-use intumescent firestop containing a synthetic elastomer. The Putty Stix expands and helps maintain a firestop penetration seal for up to 4 hours in the event of a fire, due to the intumescent property of this material. Moldability and re-enterability allows for voids to be filled in large openings and/or complex firestop systems to provide a draft and cold smoke seal for systems with L-Ratings.

The 1.4'' x 11'' Moldable Putty Stix are available for individually purchase or in a case of 10.
