SpecSeal Ready Sleeve are designed for new cabling penetrations where sleeves are required. Each Ready Sleeve kit includes a preformed steel cable sleeve with rolled edges, steel escutcheon plates with intumescent gaskets, and a dosage of our SpecSeal SSP Firestop Putty. The rolled edges of each Ready Sleeve eliminate the need for bushings while the included escutcheon plates and gaskets take the place of steel strut and strap supports.
