FRIK 4x4 Rn Installation Kit

Included in the FRIK kit is a pair of our new LDVI™ (Low Durometer Vibration Isolating) couplings, which are specifically designed for radon mitigation applications. Our patent pending LDVI couplings are molded with a softer, more flexible (low durometer) material as compared to standard plumbing couplings, making installation easier and providing superior vibration isolation.
