Couplers are added to the DPH5 model to extend the height range of the pedestal. It consists of two cylinders that screw in to each other equipped with a safety lock system that prevents overextension and ensures maximum strength. The 'ears' can be used for additional bracing and weep holes allow liquid to flow freely. Heights can be pre-set off-site or prior to installation using a combination of printed symbols on couplers, head and inverter.
