3M Fire Barrier Tuck-In Wrap Strips
3M Fire Barrier Tuck-In Wrap Strips are designed to help prevent the passage of ﬁre and smoke in new or existing non-metallic (e.g. plastic) pipe penetrations through wall or ﬂoor assemblies. 3M Fire Barrier Tuck-In Wrap Strips are engineered primarily for top-side ﬁre stop installations and help eliminate the need for retaining collars, concrete screws, ladders or most other material and equipment necessary for bottom-side installations. 3M Fire Barrier Tuck-In Wrap Strips come ready-to-install with an adhesive backed closure label (excludes WS Roll). The wrap strips can be easily installed in both concrete ﬂoor and wall assemblies, as well as gypsum wallboard assemblies.
