Ready Sleeve

• 
  SpecSeal Ready Sleeve are designed for new cabling
  penetrations where sleeves are required. Each Ready Sleeve kit includes a
  preformed steel 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.
