  • Enough putty is provided to seal the ends 1" deep for extra fire and smoke protection.
  • The Ready® sleeves are great to use in concrete floors, walls, block walls, and gypsum board - perfect for most types of construction.
  • Larger sizes of the Ready Sleeve include a built-in bushing that protects the cable jacket and allows for easy cable pulling.
  • Putty doesn't harden, so it's a snap to add or subtract cables - just make your changes, and reapply putty to original depth.
  • Standard-sized sleeves are perfect for gypsum board into which round holes can be easily drilled; larger sleeves are available for installation in masonry where drills could cause blowouts.
  • UL tested and classified in accordance with ASTM E-814, UL 1479

    Question:

    According to STI system search there is no rated system going through a wood floor/ceiling assembly. Is there another product for that application, or is it possible for this to be approved for that use?

    Asked by Anonymous user on 11.16 AM Wednesday, 26 July, 2017

    Answer:

    • - Hello, There is no testing with Ready Sleeve in floor-ceiling assemblies. Our recommendation would be to use EZ Path.
