STI SpecSeal 2″ FireStop Ready Sleeve

STI SpecSeal 2″ FireStop Ready Sleeve

The STI SpecSeal® 2″ FireStop Ready® Sleeve is a complete firestop pathway solution designed to protect cable penetrations through fire-rated walls and floors while maintaining the integrity of fire-rated assemblies. Ideal for data centers, telecommunications rooms, network closets, and structured cabling installations, this sleeve provides a clean and code-compliant solution for routing cable bundles through building barriers.

The system features a preformed zinc-plated steel sleeve with rolled edges, helping protect cables from abrasion while eliminating the need for additional conduit bushings. Each kit includes steel escutcheon plates with integrated intumescent gaskets and SpecSeal® firestop putty, which work together to seal the penetration and help prevent the spread of flames, smoke, and hot gases.

When exposed to heat, the intumescent components expand, helping maintain the fire-resistance rating of the wall or floor assembly. The ready-to-install sleeve simplifies firestop compliance while providing a professional, organized cable pathway.

Designed for new cable penetrations, the 2-inch FireStop Ready Sleeve supports structured cabling infrastructure in commercial and institutional buildings while helping meet building fire safety codes.
