innovative fire protection systems 

STI leads the industry in developing innovative fire protection systems that help stop the spread of fire, smoke and hot gases. For over 25 years, our team has worked hand in hand with the construction industry to create simple solutions to complex firestopping problems. Our SpecSeal® and EZ Path® product lines are engineered to deliver powerful performance. Because our system designs are user-driven, they are easier to apply. The result is simply designed, outstanding fire protection systems which often result in lower installed costs. STI products and systems offer innovative firestop solutions for all types of new construction and retrofit applications. Since firestopping is our only business, we concentrate all our resources on providing the highest quality, fully tested, innovative firestopping solutions.

  • Maintenance-free.

“The EZ-Path Series 22, 33, and 44+ Fire-Rated Pathways do not require regular maintenance when properly installed”…

…”Each device remains maintenance free following installation”…

EZ Path Series 22+

The EZ Path® Series 22 Fire Rated Pathway is a pathway device designed to allow cables to penetrate fire-rated walls without the need for firestopping. This device features a built-in fire sealing system that automatically adjusts to the amount of cables installed. Once installed in a fire barrier, cables can be easily added or removed at any time without the need to remove or reinstall firestopping materials.

EZ Path Series 33+

EZ Path® Series 33 Fire Rated Pathway consists of an enclosed heavy gauge galvanized steel pathway lined with intumescent material engineered for rapid expansion when exposed to fire or high temperatures, quickly sealing the pathway and preventing the passage of flames and smoke.

EZ Path Series 44+

EZ Path® Series 44+ Fire Rated Pathway is designed for easy installation in floors and walls. Tested and approved cable capacities range from 0 to 100% visual fill. EZ Path® Series 44+ Fire Rated Pathway when installed with available single wall plates is designed for new cable installations. In these installations, the device does not require mechanical attachment to either the wall or the wall framing and must be installed after the wallboard has been installed. Split floor plates and multi-gang wall and floor brackets permit installation around previously installed cables if so desired. These installations require mechanical attachment to the barrier. A list of available accessories along with their intended use is shown on page 2 under available components.

STI is the only manufacturer providing end-to-end fire and smoke sealing solutions that address the ever-changing needs of data and communications infrastructure.
