FR2 for retrofit in 2″-8″ floor drain. Flexible rubber flange, brass valve. The “F series” can be used in homes where sub-slab suction has been included as a radon mitigation technique.
Dranjer seals permit unrestricted flow of water into floor drains or sump pits while sealing out the entry of mold spores, insects and radon gas from the sub-slabe floor area.
