With a legacy of over twenty years of innovation, STI is committed to the continued growth and success of the low voltage industry. We offer a complete range of pathway solutions designed to tackle your real-world cable conditions without getting in the way of your day to day. Our EZ-Path® Fire-rated Cable Pathways are considered the industry standard in maintaining Fire, Smoke, and Acoustic Seals in the cable pathway without the burden on on-going inspection and maintenance.
With a range of mounting plate configurations EZ-Path® is the most adaptable cable pathway solution that configures to your pathway needs. Modular grid systems, single device plates, horizontal and vertical ganging plates, as well as solutions for new and existing construction make EZ-Path® the most versatile solution for achieving compliance in the cable pathway, adapting to meet your needs instead of forcing the pathway to adapt to your firestop system.
Maintenance Free Fire-rated Cable Pathway Solutions
EZ-Path Series 44+ Fire-Rated Pathways are designed for high cable volume conditions through fire-rated walls and floors while eliminating 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. Under fire exposure, the intumescent pads expand and swell resisting the passage of smoke and flame.
- Tested for cable filles ranging from 0 up to 100%
- Single device plates, high-density, horizontal and vertical ganging options designed to partner with you pathway needs and cable capacity
- Solutions for new and existing construction
- EZ Path takes care of itself with its built-in self sealing mechanism that adjusts automatically as cables are added, changed, or removed while maintaining all ratings
- High-density brackets can support up to 12 of our Series 44+ Devices into nominal 1-1/2 square feet of space, eliminating the need to individually bundle and waterfall cables as they pass through fire-rated wall and floor assemblies.


Scalable Solutions for Smoke & Acoustic Partitions
Designed for easy installation in non-rated floors and walls, EZ Path Series 44NEZ Smoke & Acoustical Pathway provides exceptional leakage and acoustical performance with tested and approved cable capacities ranging from 0 up to 100% visual fill. A single unit has equivalent cable capacity to the Series 44+ Fire-Rated Pathway providing consistency of performance across the low-voltage pathway regardless of barrier type.
- Partners with EZ-Path Fire-rated Pathways to provide consistent experience and performance regardless of barrier rating
- Single and Gang configurations available
- Exceptional air leakage and acoustical performance
Restoring Compliance in Existing Cable Pathways
Non-compliant cable sleeves are the bane of every facilities team. EZ-Path Retrofit Devices brings deficient openings back into code compliance quickly. The two-part clam shell design installs easily around cable sleeves to restore fire and smoke leakage performance. The EZ Path Retrofit Device retrofits cable sleeves from 50% up to 100% visual fill, restoring fire performance without the need for additional firestop products.
EZ-Path Cable Tray Retrofit Device quickly and easily remediates existing cable trays with cable fills of 25 up to 100% visual fill restoring fire performance without the need for additional firestop products. Its two-part design installs around non-compliant cable tray penetrations, restoring fire and smoke leakage performance.

Solutions for Security, W.A.P., and B.A.S. Cable Penetrations
EZ-Firestop Grommets make sealing penetrations of individual and small bundles of cables through gypsum board walls a snap. Molded from premium plenum-plastics and incorporating a soft foam inner core, EZ-Firestop Grommets eliminate the need for sleeves, firestop putties & sealants.
- Great for single membrane or complete through-penetrations
- For single or multiple cables
- Ideal for Alarm, Security or Wireless Access Point installations
- Designed for 1 & 2 Hr Fire-rated Gypsum Board Wall assemblies
- Professional finished appearance
The EZ-Path® Family of Cable Pathway Solutions
EZ Path® Fire-Rated Pathways are the only self-sealing fire and smoke devices that are exempt from maintenance requirements. EZ Path® Pathways have no moving parts and require no action to activate the internal sealing mechanism, making them the only rated firestop device that are compliant right out of the box.

An Evaluation Service Report (ESR) was recently issued by UL® for our EZ Path® Fire-Rated Pathways confirming code compliance with the International Building Code® (IBC), International Fire Code® (IFC), and NFPA 101, “Life Safety Code®” (LSC). The report goes on to confirm that, when properly installed, the device is exempt from ongoing maintenance.
Ease of System Selection and Submittal Generation
Guided search for finding the right firestop system for your condition and building Firestop Submittals for submission to your AHJ.

- Integrate user documents, company logos, and Engineering Judgements
Firestop Penetration Design and Collaboration in Revit
Firestop Clash Management® (FCM) is our Autodesk® Revit® Plugin that takes the guess work out of firestop solution design and selection. Utilizing clash detection and model parameter data, FCM scans your model detecting locations where construction joints and penetrations occur and recommends appropriate firestop systems at these locations. Additionally, FCM places marker and product objects within the model ensuring that system selection are present within the model and accessible to project team members.
- Automates system selection and placement within the mode
- Functions at your workstation, no need to manually export to third party systems/services
