STI SpecSeal 2″ FireStop Ready Sleeve with Large Plates
The STI SpecSeal® 2″ FireStop Ready® Sleeve with Large Plates is a complete firestop pathway solution designed to protect cable penetrations in fire-rated walls and floors while maintaining a clean, professional cable entry point. Ideal for data centers, telecom rooms, and structured cabling installations, this ready-to-install sleeve simplifies code-compliant firestop installations.
This system includes a preformed zinc-plated steel sleeve with rolled edges, eliminating sharp edges and removing the need for additional conduit bushings. The kit also includes oversized escutcheon plates with intumescent gaskets and SpecSeal® firestop putty, which work together to seal the opening and help prevent the spread of flames, smoke, and hot gases through wall penetrations.
The large escutcheon plates provide extra coverage for oversized or irregular wall openings, ensuring a clean finished appearance while maintaining the integrity of fire-rated assemblies. This makes it especially useful in retrofit installations or projects where the wall penetration may be larger than standard openings.
Designed for new cable penetrations where sleeves are required, the 2-inch Ready Sleeve supports structured cabling pathways and helps maintain compliance with building fire safety codes in commercial and institutional environments.
