The HOLDRITE HFPE6 HydroFlame Pro Extension Sleeve is designed for use with #6 Firestop Sleeves and #7 Hollow Sleeves. It extends the height of HydroFlame Pro Series sleeves, and accommodates 4 to 6 inch penetrant pipes. The patented telescoping design eliminates the need to cut sleeves on the jobsite. The integrated threaded cap allows for easy non-destructive removal and meets OSHA hole cover requirements.
The Holdrite HydroFlame Pro Series Extension Sleeve provides a water seal for unwanted water intrusion while still protecting against the spread of fire, smoke, and gases.
