STI SpecSeal 1″ FireStop Ready Sleeve

STI SpecSeal 1″ FireStop Ready Sleeve

The STI SpecSeal® 1″ FireStop Ready® Sleeve is a compact firestop pathway solution designed to seal small cable penetrations through fire-rated walls and floors while maintaining the integrity of fire-rated assemblies. Ideal for structured cabling, telecommunications, and low-voltage installations, this ready-to-install sleeve provides a clean, organized, and code-compliant cable pathway.

The system features a preformed zinc-plated steel sleeve with rolled edges, which helps protect cables from abrasion and eliminates the need for additional conduit bushings. The kit includes steel escutcheon plates with integrated intumescent gaskets and SpecSeal® firestop putty, creating a secure seal around the cable bundle.

When exposed to high temperatures, the intumescent materials expand, helping block the passage of flames, smoke, and hot gases while maintaining the fire rating of the wall or floor assembly. The compact 1-inch sleeve size is ideal for smaller cable bundles and single conduit penetrations often found in network closets, telecom rooms, and equipment rooms.

Designed for new cable penetrations, the SpecSeal FireStop Ready Sleeve helps installers maintain building code compliance while keeping cable pathways organized and protected.
