No coupling is required to connect the extension to the base sleeve, simplifying installation and reducing the number of components on the job. This part is used in passive fire protection assemblies where pipe penetrations pass through concrete floor or wall assemblies. It is installed by licensed plumbers and fire protection contractors working to applicable code requirements.\u003c\/p\u003e\n\u003cp\u003eThe HFPE4 is intended for use on concrete pours greater than 12 inches where the standard sleeve height is insufficient. It is available to match all HOLDRITE HydroFlame Pro Series sleeve sizes, making it a consistent fit across a full firestop assembly. The extension connects to safety caps, water dams, water modules, and the underside of sleeves, giving it broad utility throughout the HydroFlame Pro Series system on both residential and commercial projects.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExtends sleeve height up to 4.75 inches in 0.25-inch increments for precise height adjustment\u003c\/li\u003e\n  \u003cli\u003eNo coupling required for connection to base sleeves\u003c\/li\u003e\n  \u003cli\u003eCompatible with all HOLDRITE HydroFlame Pro Series sleeve sizes\u003c\/li\u003e\n  \u003cli\u003eConnects to safety caps, water dams, water modules, and the underside of sleeves\u003c\/li\u003e\n  \u003cli\u003eDesigned for concrete pours exceeding 12 inches in depth\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with all HOLDRITE HydroFlame Pro Series sleeve sizes.
