The CASH-ACME HFPE4 is a firestop extension sleeve designed to increase the installed height of HOLDRITE HydroFlame Pro Series sleeves by up to 4.75 inches in 0.25-inch increments. 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.
The 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.
Compatible with all HOLDRITE HydroFlame Pro Series sleeve sizes. Connects to HydroFlame Pro Series safety caps, water dams, water modules, and sleeve undersides.
Installation should be performed by a licensed plumber or qualified fire protection contractor in accordance with applicable building and fire codes. Confirm sleeve size and concrete pour depth before selecting extension height. No coupling is needed for attachment to the base sleeve. Ensure all firestop assembly components are installed per the manufacturer assembly listing to maintain the fire-resistance rating of the floor or wall penetration.
