SpecSeal® Ready Split Sleeve kits provide a fast, code‑compliant solution for creating firestopped cable sleeves around existing cables. Designed specifically for retrofit applications, each Ready Split Sleeve kit includes two preformed steel sleeve halves with rolled edges, steel escutcheon plates with integrated intumescent gaskets, and a premeasured dose of SpecSeal SSP Firestop Putty for effective sealing. The Ready Split Sleeve’s two‑piece steel body and matching split escutcheon plates are engineered to easily capture previously installed cables, allowing installers to form a secure sleeve around active cable bundles without disrupting system operation. Once assembled, the sleeve fastens tightly to the penetrated barrier, delivering a clean, durable, and fully compliant firestop sleeve. Ideal for commercial and technology‑heavy environments, SpecSeal Ready Split Sleeve kits simplify retrofit cable penetrations while providing consistent fire, smoke, and air‑leakage resistance.
