Eaton Specification Sheet - FSP-MPP-9X9
The FSP-MPP-9X9 is a pliable, moldable putty-based fire stop designed for cable tray penetrations, delivering faster installation, fewer patch repairs, and a consistent barrier even on irregular openings. In practice, technicians can apply it around multiple cables in a single operation, avoiding messy caulking and time-consuming barrier rebuilding. Adhesion and conformability are built-in, so it adheres to varied substrates and ages well, reducing the risk of cracking or gaps over time. The large 9.5 in x 9.5 in pad simplifies alignment with Eaton B-Line series components and provides ample coverage for common tray openings, cutting installation time and material waste. UL Classified certification provides regulatory assurance, supporting compliance with industry safety standards and facilitating approvals. Compatibility with the B-Line system and 3M barrier materials helps streamline procurement and field installation, delivering measurable labor savings and reduced downtime for critical electrical infrastructure.
