Marketing InformationGet the same advanced sleeve design even when others provide fire stopping or you want more annular space. HydroFlame™ Pro Series hollow sleeves don't include intumescent material but can achieve two or three hour F ratings with use of HydroFlame™ firestop sealants. This fast, simple concrete sleeve for flat form decks comes with a cap that allows you to adjust the height of your sleeve in quarter-inch increments and remains in the slab, unlike typical hollow sleeves.
