The Liberty GR22NS-FL is a 2" female NPT discharge non-sparking guide rail with a bronze claw for hazardous-location installations, fitted for XFL50/XFL70/XFL100/XFL150-Series explosion-proof pumps. All GR-Series rails use a rugged one-rail design with an auto-guide feature, a 1-1/4" NPT guide pipe connection (pipe not included), a heavy-duty nitrile sealing grommet, a cast iron upper rail support bracket, and a powder coat finish for corrosion resistance.
