STI Firestop Announces New ProductsSTI Firestop has announced new additions to its EZ-Path® line of firestop products.

Like cable and connectivity products, firestop products also must evolve to meet constantly changing demands. The modular nature of the STI Firestop EZPath® Fire-Rated Pathways allows the creation of new, adaptable and higher-density bracketing solutions to match the growth of a physical plant. STI developed four new wall bracket styles for the EZ-Path® Series 44+ Fire-Rated Pathways that complement existing bracket offerings while providing greater cable densities and pathway design flexability.

The EZ-Path® Series 44+ Fire-Rated Pathway is designed for high cable volume conditions through fire-rated walls and floors to eliminate the burden of ongoing maintenance. The Series 44+ incorporates self-sealing intumescent pads that automatically adjust to the installed cable fill without the need for user manipulation. During fire exposure, the intumescent pads expand and swell to resist the passage of smoke and flame.

EZ-Path® Series 44+ Fire-Rated Pathway comprises:

  • Self-sealing design provides exceptional fire and smoke leakage ratings
  • Allows for easy moves, adds, and changes
  • Designed for new and existing conditions
  • Variety of accessories available for any field condition
  • Modular grid system for riser applications
  • Greatest achievable cable density of any solution on the market


The EZ-Path® Series 44+ Multi-Gang Vertical Wall Bracket (Cat. No. EZP544WV) allows for ganging of 1-5 devices vertically up a wall cavity instead of horizontally across it. This new bracket provides the same density and capacity of cables as our existing EZ-Path® Series 44+ Multi-Gang Wall Bracket (Cat. No. EZP544W) while providing designers additional flexibility in orientation of their cabling pathway without sacrificing fire-ratings, leakage performance, or cable density.

The EZ-Path® Series 44+ Dual Bank Multi-Gang Wall Bracket (Cat. No. EZP544WD) further expands on the cable capacity and density of the EZ-Path® Series 44+ Multi-Gang Wall Bracket (Cat. No. EZP544W). This bracket allows for up to 10 Series 44+ devices to be installed, in two banks each consisting of up to five devices, while still fitting between standard 24-in. OC stud spacing. The increased density of devices provides a cable loading area of 68% of the wall space used, while competing solutions utilizing a similar amount of wall space only allow for a loading area of 36%. In other words, a single EZP544WD bracket completely populated with devices can accommodate up to 2,100 Cat6 Cables (OD of 0.236 inches).

The EZ-Path® Series 44+ Six Gang and Twelve Gang Wall Brackets (Cat. No. EZP644W & EZP644WD, respectively) provide high cable capacity and density in wall penetrations, accommodating cable trays of up to 24-in. wide loaded to 100% fill without problems arising. The two new brackets were designed for applications such as data centers where pathway cable density is paramount (Cat. No. EZP644WD) as well as in congested ceiling spaces where wider, shorter trays are used over narrower, deeper, or multiple trays (Cat. No. EZP644W). When fully populated, the EZP644W bracket can accommodate 1,260 Cat6 Cables (OD of 0.236 inches) while the EZP644WD bracket can manage up to 2,520 Cat6 Cables (OD of 0.236 inches).
