New Ready Sleeve™ From STI

Provides Simple, Cost-Effective Firestop Protection for Electrical, Telephone and Data Cables; Ready to Install Out-of the-Box Kit Requires No Additional Parts or Fabrication

Specified Technologies, Inc. has introduced SpecSeal® Ready Sleeve™, an economical solution for firestop protection and support of electrical, telephone, or data cabling passing through rated or non -rated fire barriers. Because the sleeves are supplied ready to install in an out -of -the -box kit and require no field fabrication, material and labor savings are significant.

The kit includes a 12 in. (300 mm) long steel sleeve available in 1, 2, or 4 in. (25, 51, or 102 mm) diameter; corresponding sized steel escutcheon plates which lock the device in place; and SpecSeal® Firestop Putty to seal the ends of the sleeve to the required 1 in. (25 mm) depth.
The UL® Classified Firestop Sleeves require no cutting, which means no waste. Sleeves are conveniently sized for up to 10 in. (250 mm) thick barriers. Sleeve ends are rounded smooth to protect cable jacketing and eliminate the need for plastic bushings (bushing supplied with 1" sleeve.) No support struts and clamps are required because the escutcheon plates sandwich the barrier and lock the sleeve into place. Intumescent firestop gaskets on the escutcheon plates provide an external firestop seal that meets code requirements, eliminating the need to install firestop sealant around the steel sleeve.
Ready Sleeve™ Firestop Sleeves are suitable for use in all common wall constructions including concrete walls, concrete block walls and gypsum board/stud wall assemblies up to 10 in. (250 mm) thick.
